sugar. Because the electrons increase in potential energy as they move from water(H-O bond) to sugar(C-H bond), this process requires energy—in other words is endergonic. This energy boost is provided by light. In cellular respiration, the summary equation is  Glucose loss electrons and become oxidized, oxygen get electrons and become reduced, so this reaction is redox reaction. In cellular respiration, C-H bond are broken and release energy as the electrons from hydrogen form H-O bonds in

Energy is the ability of matter to do work. Matter is anything that occupies space and has mass. Potential energy is energy that is stored and ready to do work and kinetic energy is energy in motion. Energy comes in different forms: light, heat, electrical, chemical, and mechanical. This energy can be converted from one form to another and this is called the first law of thermodynamics. This law states that energy can change from one form to another but it is neither created anew nor destroyed

study of energy and it’s transformations, there are two laws that apply to everything in the universe. These laws, known as the 1st and 2nd laws of thermodynamics, describe the flow of energy throughout an ecosystem, and also how the process of transferring energy provides the means to sustain life within it. The rainforest is a very complex ecosystem that contains many different species of animals, insects, plants, and trees. The 1st law states that an organism can not create the energy it needs

Essential Facts for Physical Science Scientific Investigation, Reasoning, and Logic 1. SI (metric) measures, recognized around the world, are a standard way to make measurements. 2. Bar graphs, line graphs, and circle graphs are powerful tools for displaying and interpreting data. 3. To communicate the plan of an experiment accurately, the independent variable, dependent variable, and constants must be explicitly defined. 4. The number of repeated trials needs to be

popular for remote area power generation applications due to advances in renewable energy technologies and subsequent rise in prices of petroleum products. A hybrid energy system usually consists of two or more renewable energy sources used together to provide increased system efficiency as well as greater balance in energy supply. Hybrid renewable energy systems is one of the most promising applications of renewable energy technologies in remote areas, where the cost of grid extension is prohibitive

Thermodynamics is a branch of physics concerned with heat and temperature and their relation to energy and work. It defines macroscopic variables, such as internal energy, entropy, and pressure, that partly describe a body of matter or radiation. It states that the behavior of those variables is subject to general constraints, that are common to all materials, not the peculiar properties of particular materials. These general constraints are expressed in the four laws of thermodynamics. Thermodynamics

Thermodynamics is the area of science that includes the relationship between heat and other kinds of energy. Thermodynamics was discovered and studied beginning in the 1800s. At that time, it was linked to and gained importance because of the use of steam engines. Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Nicolas Leonard Sadi Carnot . Who believed that the efficiency of heat engines

nucleon to change? When to two atoms comes together a pieces of mass is lost and converted into energy. 5. What is fission? Fission is when the nuclease of an atom splits into smaller pieces. 6. How does mass per nucleon change in a fission reaction? 7. How does the equation E=mc2 relate to mass per nucleon? It can find how much energy different amounts of mass can create. 8. Where does the energy released in a fusion or fission reaction come from? Is comes from the missing mass that was

Africa use renewable energy sources as a solution to its energy crisis? The great demand for renewable energy sources has been on a rise in South Africa since it experienced its energy crisis, namely load shedding. The load shedding occurrence is due to the non-renewable sources of energy which are diminishing. Renewable energy is a clean energy source which can be generated or manufactured faster than it can be used up. Most renewable energy sources are clean sources of energy (e.g. they don’t emit
