The total potential and kinetic energy of all the particles in an object
Heat
The transfer of thermal energy from one object to another because of a temperature difference
Temperature
The measure of how hot or cold an object is compared to a reference point
Fahrenheit (°F)
Of or relating to a temperature scale that registers the freezing point of water as 32°F and the boiling point as 212°F at one atmosphere of pressure
Celsius Scale (°C)
A temperature scale where the freezing and boiling points of water are chosen as reference points.
Kelvin Scale (K)
A scale at which the reference point is at which all motion of particles ceases.
Absolute Zero

Conduction
The transfer of heat with no overall transfer of matter
Convection
The transfer of heat when particles of a liquid or gas move from one point to another
Radiation
The transfer of heat by waves moving through empty space
Thermal Conductor
