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

The temperature at which all motion of particles inside a sample of mass ceases.

Specific Heat

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
