exothermic reaction
An exothermic reaction is a chemical reaction that releases energy by light or heat
thermochemical equation
A Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH
calorimeter
A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity
Heating things up increases the entropy
Entropy is a measure of the energy of a system that is unavailable for doing useful work
endothermic reaction
The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings; usually, but not always, in the form of heat
joule
The joule , symbol J, is a derived unit of energy in the International System of Units
