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?
