Temperature

In general, temperature is a measure of average translational kinetic energy of particles — see Relationship between Kinetic Energy and Temperature.

Temperature should always be measured using the Kelvin scale Changes in temperature () can be measured with a thermoscope — adding or subtracting temperature (by Heat) results in some macroscopic change.

For gases, temperature is ==only a meaningful quantity when the gas is in Thermal equilibrium with its environment== (the same goes for Pressure). Temperature is defined by the Zeroth Law of Thermodynamics — without this law it would be impossible to say that two objects shared a common quantity of temperature between them.
