heat released by three reactions. To do this experiment we need to know about heat which is energy that is being moved because of temperature change between two things. Enthalpy which is a special energy function to make the process of finding how much energy is released or absorbed by a given reaction. Enthalpy is presented by Δ H or Q. Δ represents “a change in” and H represents” heat”. Q represents energy required. To know the reactions presented we must know what the meanings of, exothermic which

form of ice which has the highest albedo. Therefore the ocean interacts with the Sun’s radiation by reflecting and absorbing the heat energy. 2. The amount of energy Earth absorbs is equal to the amount of energy it radiates. Why is this important? Explain your answer. It’s important that the amount of energy Earth absorbs is equal to the amount of energy it radiates because on Earth we need to keep the temperature at a sustainable temperature, meaning the Earth can’t be too hot or too cold

the light energy captured from the sun into chemical energy that can be used to fuel the organism's activities”. (http://en.wikipedia.org/wiki/Photosynthesis) A solar cell “is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. (http://en.wikipedia.org/wiki/Solar_cell) Photosynthesis and a semiconductor-based solar cell have several similarities and differences. Photosynthesis and solar cells both require solar energy or sunlight

The Energy Document “Be humble, for you are made of earth. Be noble, for you are made of stars.” -Serbian Proverb Science can only talk about what it can measure and it cannot measure thoughts, love, spirit, or God; therefore, it cannot scientifically talk about those things. Science measures the physical make-up of the universe and talks about how it happened, not who made it. An obvious example of this is the illusion of conflict between creationist and evolutionist. They argue as
