Calorimetry by Zach

Summary:
            During this topic we learned about how to measure heat using calorimetry. There are two different types of chemical reactions, endothermic and exothermic reactions. An endothermic reaction is a reaction where heat is absorbed so the object would get cooler. An exothermic reaction releases heat so then the object undergoing the reaction would heat up. Heat is measured in a unit called calories. A calorie is the amount of heat needed to raise one gram of water one degree celsius.

Why is this important:
            This is an important topic because it helps the chemist know what will happen when some different reactants are mixed together. A chemist not only needs to know whether a reaction takes in energy or gives off energy but also needs to know exactly how great the energy change will be per mole of reactant. If this is known then the chemist will be able to control the reaction by limiting the total amount of reactants and by regulating the flow of energy into or out of the reaction vessel.




Question to the Public:

            How is calorimetry used in the real world?
