Calorimeter - a device used to measure the heat released or absorbed during a chemical reaction
Closed system - a system that can exchange only energy with the surroundings
Endothermic - a process during which heat enters a system
Enthalpy - the total energy of the system plus the pressure times the volume
Exothermic - a process during which heat leaves a system
Hess' law - a law stating that the enthalpy change of a physical or chemical reaction depends only on the initial and final conditions
Isolated system - a system that cannot exchange either energy or matter with the surroundings
Open system - a system that can exchange both matter and energy with the surroundings
Specific heat capacity - the amount of energy required in order to increase the temperature of a given mass of substance by one degree.
Thermal Energy - the sum of all the kinetic energies of all the particles of a sample of matter
Thermochemistry - the study of the energy changes involved in chemical and physical processes
