Temperature is a measure of the average kinetic energy of a gas?

[Avanthica]

Main Question or Discussion Point

Why do they say temperature is a measure of average kinetic energy how is this possible. how can we take it is it applicable for all types of gases?

Apparently all types of gases behave very similarly -- almost like an ideal gas .

For such an ideal gas one can derive velocity distributions $\Rightarrow$ kinetic energy distributions that have a parameter $T$. And that parameter $T$ we call the temperature.

It is not applicable for all types of gasses. It is only applicable for ideal monoatomic gasses. For other gasses thermal energy involves other forms of internal energy

other forms of internal energy

What are the other forms of internal energy taken here?

Rotational, vibrational, electronic, etc.
