(45 cards)
A measure of the average kinetic energy of the particles in a substance
Temperature
The energy of a substance due to both random motions of its particles and to the potential energy that results from the distances and alignments between the particles
Internal Energy
The state in which two bodies in physical contact with each other have identical temperatures
Thermal Equilibrium
The energy transferred between objects because of a difference in their temperatures
Heat
The quantity of heat required to raise a unit mass of homogenous material 1K or 1 °C in a specified way given constant pressure and volume
Specific Heat Capacity
An experimental procedure used to measure the energy transferred from one substance to another as heat
Calorimetry
The physical change of a substance from one state to another at constant temperature and pressure
Phase Change
