Heat is a type of energy.

Heat is the name for the type of kinetic energy possessed by particles.

If something gains a lot of heat energy, it becomes hot – so what is temperature?

Heat energy is measured in joules (J).

How many joules are there in a kilojoule (kJ)?

Temperature is a measure of how hot or cold an object is.

(It is not the total amount of energy contained in the object.)

Temperature is measured in degrees Celsius (ºC).

The freezing point of water is defined as 0ºC (at 1 atm.).

The boiling point of water is defined as 100ºC (at 1 atm.).

Temperature can be measured by a variety of different thermometers. These include liquid in glass, digital, thermocouple and bimetal strip thermometers.
