...have believed that adding salt to water will help it boil faster, even your mum does it but does it really help?When testing this experiment we found that 25g of salt would change the solution of 1l of water . we found that you have to use the same heat source for this experiment to make sure that the results stay constant and after that you have to allow for your heat source to cool. The boiling temo of water is 100 d C but when water is added the solution is changed so much that it increases the boiling tempreture buy two degrees (mental-floss,2005) Infact, adding salt to your water does not lessen time taken to boil water Adding salt to water can increase the time taken to boil by up to 30 seconds. While experimenting we found that the time increased the time but up to 30 seconds. this can be proven in our results that were done numerous times to prove our theory and eliminate human error. Going up un 15g gave us and idea of how much it changes per 15g . the first 15-25 g there was very little change, this being said it changed by 5 – 10 seconds. And at 75g of salt we saw out biggest change of about 30s At 75g it reaches equilibrium and after that , no amount of salt added would change the time. We tried adding 100g salt to the 1l of water but found that the average boiling time stayed the same as the 75g of salt before. This is because in every solution at one point it will reach constant and at this point only changes to the amount of water would change the outcome Claim3 ...

...Does Salt effect the Boiling Temperature of Water? By Jason Project Design Plan Water freezes at 32°F and boils at 212 °F. Dissolved substances such as salt lower the freezing point of water. This is why salt is sprinkled over icy pavement or wet roads in winter. It causes the temperature of the water to reach less that 32°F to form ice. Does it also have an effect on the boiling point of water? Does the quantity of salt added effect the boiling point? My experiment is to find out what effects salt will have on the temperature of boiling water. The hypothesis of my experiment is that if I add more salt then the temperature of the boiling water will increase. I believe the more salt added to the water the higher the boiling temperature is going to be. I will be using 2 cups of water as a base in a 2 quart stainless steel pot. I will add 1 tsp of salt, 2 tsp of salt and 4 tsp of salt and measure the temperature of the water. Literature Review If you heat up two pots of water one with tap water and one with tap water and 20 percent salt water, the pot with the salt water will boil before the pot without salt water. The heat capacity of water is higher than salt water. This means that it takes less energy to increase the temperature of salt water than it does unsalted water. Thus salt water warms up quicker and gets to a boiling point faster than unsalted water. (Dammann, 2013) Dissolving table salt into water will lower the overall vapour pressure of...

...Investigation Plan PROBLEM Does sugar, salt, and baking soda affect the boiling point of water? HYPOTHESIS My hypothesis is that those materials will not affect the boiling point. PROCEDURE To begin my experiment, I will buy a measuring cup, baking soda, and thermometer at a grocery store. The measuring cup will measure to a cup, and the thermometer will be a glass thermometer so it will not break when water gets hot. In a pot, I will take two cups of tap water until it reaches to 212 degrees. Then I will take ½ cup sugar and add it to the 212 degree water and take the thermometer and put in the water and test to see if the temperature of the water changed....

...they kill the lobsters by stabbing them in the brain with a knife. However, he points out that the majority of a lobster’s nerve bundles, are “on the underside, from stem to stem, and disabling only the frontal ganglion does not normally result in a quick death unconsciousness” (Wallace 63). He wants his readers to see both sides of the controversy between animal rights activists and gourmet food lovers. He states his opinion but he remains non bias to keep an open minded flow to the ideas that he is presenting throughout his essay. People think it would hurt the lobsters less when they put them into cold water and slowly bring it to a boil, as their body would adjust to the temperature as it increases to the eventual 212 degrees Fahrenheit. This is, unfortunately, not a humane way to kill a lobster. He states that the lobsters can feel a change of only a degree or two in water temperature. That is why they often travel 100 or more miles per year in order to find the temperature they like. The questions he presents is how, if the lobsters are highly sensitive to temperature, is it really humane to boil them to death, just so that they can be enjoyed by the...

...beating the rice. Our parents’ tasks were to perform all of the tasks, and at the same time oversee them. We named ourselves the picker, the counters, the beaters, and overseer respectively. Once our assigned tasks are complete, and the goal of the day is met, we then sit together around the camp fire during meals time, and eat together while connecting with each other through conversation. The children will all eat together from the same big dish, while the adults eat together from the same big dish. My family was not selfish with the rice that we planted and harvested. We shared the rice with family, friends, and even sold some to the community. My family was well known for its generosity. Rice can be prepared by cooking it in boiling water. You can eat it with stew, soup, butter, or...

...Temperature and Response time measurement Abstract In this experiment, a Resistive Thermal Device (RTD) and thermocouple were calibrated for first order measurement. Then, the response times of the RTD and thermocouple sensors were calculated. After performing this experiment, it was found that the time constants for the RTD were found to be -78.7 for cold to hot and 17.39 for hot to cold. The time constants for the thermocouple were found to be 3.519 for cold to hot and 2.64 for hot to cold. The rise times for the RTD were found to be 7.39 for cold to hot, and 7.9 for hot to cold. The rise times for the thermocouple were found to be 1.14 for cold to hot, and 1.27 for hot to cold. The error band for the RTD was found to be ±.0075, and the error band for the thermocouple was found to be ±.3887. Nomenclature T Time τ Time Constant E Error Band INTRODUCTION A Resistive Thermal Devices is a sensor used to measure the temperature by correlating the resistance of the RTD element with temperature. An RTD most commonly consists of a length of fine coiled wire wrapped around a glass or ceramic center. The element of the RTD is made of a pure material so its resistance can be calculated at various temperatures [1]. A thermocouple is that consists of two conductors which produce a voltage proportional to a temperature difference between either end of the pair of conductors. This allows for the measurement of the temperature at broad ranges...

...any guilty eating lobsters. Wallace sounds so depress and he also says, “Gourmet readers should also consider moral status and suffering that animal involved.” RESPONSES David Foster Wallace’s Essay, Consider the Lobster has raised a great point. How Humans treat animals, especially in America. I really enjoyed reading this essay. Being a vegetarian I am really impressed by the author’s writing. Wallace is not telling people to become vegetarians or vegans. Many people think lobster don’t have brain so they don’t feel pain. Wallace states that “It is difficult not to sense that they're unhappy, or frightened, even if it's some rudimentary version of these feelings,” showing his knowledge of the way lobsters react to the pot of boiling water. Also he says, “even if it's some rudimentary version of these feelings and, again, why does rudimentariness even enter into it?” Showing that we shouldn’t base whether or not we should treat them better based On what the pain level they feel. Wallace uses of both ethos and pathos is very convincing to put second thought to eat live...

...above. In another section of this series I described the several types of cavitation, so in this paper I want to talk about another side of cavitation and try to explain why the above happens. Cavitation implies cavities or holes in the fluid we are pumping. These holes can also be described as bubbles, so cavitation is really about the formation of bubbles and their collapse. Bubbles form when ever liquid boils. Be careful not to associate boiling with hot to the touch. Liquid oxygen will boil and no one would ever call that hot. Fluids boil when the temperature of the fluid gets too hot or the pressure on the fluid gets too low. At an ambient sea level pressure of 14.7 psia (one bar) water will boil at 212°F. (100°C) If you lower the pressure on the water it will boil at a much lower temperature and conversely if you raise the pressure the water will not boil until it gets to a higher temperature. There are charts available to give you the exact vapor pressure for any temperature of water. If you fall below this vapor pressure the water will boil. As an...

By dismantling the rice cooker, we are required to produce the sketches of any 12 parts of the rice cooker using multi-view and isometric techniques, and also 2D drawing using Auto-CAD. In other words, this project also helps us to be a step closer in becoming engineers by teaching us how to implement the engineering drawing techniques from sketching and then translating those sketches into the final product. In this project, 3 of us are required to produce drawings of 12 parts found in a rice cooker. We are also required to measure the parts using suitable apparatus in order to obtain the most accurate measurements possible. After getting the measurements of each dimension, we are required to sketch the parts in multi-view and isometric perspectives. We are, then, required to make 2D drawing of each part using Auto-CAD with its dimension. Introduction Rice cooker is an electric kitchen appliance that is used to boil or steam rice. The essential components that are in the rice cooker are the heating element, the aluminium inner bowl, the ceramic-based outer body, the cover, the switch, the fuse and the heat sensor.

... As the Earth completes yet another turn around it axis, the sunlight pours into my bedroom indicating it is time to wake up. In case I miss the hint, my alarm clock set, as usual, for seven o’clock will do the trick. I get up and enter the bathroom, pleasantly warm thanks to the radiator fed with hot water through a series of pipes connected to a central heating boiler. I remain a couple of extra minutes under the shower enjoying the warm water – courtesy again of my boiler -, and finally I am ready to get dressed, opting for a suit cut out of one of these new fabrics that are comfortable, warm and light all at the same time. In the kitchen, I prepare breakfast for four. I turn on the electric kettle to boil water for tea, while a jar of milk heats in the microwave. I turn on the gas oven to warm up the brioche I baked yesterday. It smells delicious and it looks even better, golden and spongy due to the work of yeast. And, while the rest of the family comes down to have breakfast, I turn on the radio to listen to the latest news around the Globe. I have been awaken for just some twenty minutes and science is all around me: the movement of planets, the electricity, the water treatment, the transformation and piping of the gas we use to cook and heat out homes, the chemistry behind new fabrics, the radio waves or the power of the small fungi we use for our pastries. Whatever I do, whatever I see, science is at the heart of everything. And the day has just begun. What about...

...years until I met my wife. My wife opened my eyes to the fact that veggies didn’t have to be boiled and flavorless. I can remember the day, March 17, 1988 to be exact, when she decided that she would cook for the both of us. She made a simple chicken dish but she also cooked broccoli as a veggie side. At first I was apprehensive, but I told her that I would always try something once just in case I liked it. I never knew that cooked broccoli could have so much flavor. I was amazed by the thought of cooked broccoli that had a crunch and wasn’t a bleached shade of army green but almost evergreen in color. I ate the entire thing of broccoli. We talked about how she was taught to prepare vegetables and she was surprised that I only knew the boiling way. Afterwards she changed my opinion on many vegetables that for years I shunned at the...

...Brandi Candelaria Dr. Stewart Engl. 1302 February 3, 2016 Food Recipe Chicken and Rice The story of my recipe tells a little bit about the very first dish I cooked growing up with my aunt. I grew up in Annville Texas which is about15 minutes away from Corpus. In this area with a high population of Mexicans, one dish that is liked by many is Spanish rice. Which when it comes to rice I rather not eat it. In my entire life since I was younger I always made a big deal on not eating rice, because I personally did not like it while everyone else did. I just did not like the texture of it and also the way it tasted and ever since then I just completely stay away from any types of rice. Then one evening during December when it was freezing outside I went over to my Aunt Shana’s house, which she makes the most comforting things to eat in this kind of weather, and to go and hang out with her and my older cousin. When it came to going over there I would always get excited to go and visit because she cooks frequently and it’s always so delicious; but when I have smelled the food in past as she is cooking it reminds me of when we would always get together with everyone and have family night. I felt lucky to have had the opportunity to be surrounded by family that appreciates spending time together. So when I went over the next time Shana was in the kitchen about to start cooking. But before she started preparing the meal I wanted to help her with the cooking and so I asked...
