conduction : kinetic energy is transferred when particles collide.
thermal equilibrium : the rate of energy flow between two objects is equal and the objects are at the same temperature.
heat : flows from hot to cold.
convection : occurs from the motion of fluid in liquid or gas that is caused by difference in temperature.
radiation : thermal transfer of energy by electromagnetic waves.
specific heat : the amount of energy that must be added to the material to raise the temperature.
thermodynamics : is the study of heat.
kinetic molecular theory : matter is made up of tiny particles in motion
thermal energy : is the overall energy of motion of all particles making up the object.
temperature : is the "hotness" of the object.
absolute zero : is the temperature where all molecular motion stops.
calorimeter : a well insulated device used to measure changes in thermal energy.
heat of fusion : amount of heat required to change from solid to liquid.
heat of vaporization : amount of heat required to change from liquid to gas.
first law of thermodynamics : change in thermal energy of an object is equal to the heat that is added to the object.
second law of thermodynamics : natural processes go in a direction that maintains or increases the total entropy of the universe.
heat engine : a device that continously converts thermal energy to mechanical energy.
entropy : a measure of the disorder in a system.
heat pump : uses work to remove heat energy.
