Kinetic Energy the energy an object has due to motion.
Pressure the result of a force distributed over an area
Absolute Zero a temperature of 0 kelvins.
Charles Law the direct proportion of the volume of a gas to its temperature(in kelvins)if the pressure and the number of the particles of the gas are constant.
Boyle's Law the inverse variation of the volume of a gas with its pressure if the temperature and the number of particles are constant.
Phase Change a reversable physical change that occurs when a subtance changes from one state of matter to another.
Endothermic a description of a change in which a system absorbs energy from its surroundings
Heat of Fusion the energy a subtance must absorb in order to change from a solid to a liquid.
Vaporization the phase change in which a subtance changes from a liquid to a gas.
Heat of Vaporization the energy a subtance must absorb in order to change from a liquid to a gas.
Evaporation The process that changes a subtance from a liquid to gas when its temperature as below the boiling point.
Vapor Pressure The pressure caused by the collisions of particles in a vapor with walls of a container.
Condensation the phase change in which a subtance changes from a gas or vapor to a liquid.
Sublimation the phase change in which a subtance changes from a solid to gas or vapor without changing to a liquid first.
Deposition the phase change in which a gas or vapor changes directly into a solid first changing into a liquid; the placement of sediment that has been transported from another location.
