How does the kinetic energy of particles vary as a function of temperature?

It is directly proportional

Explanation:

For an ideal gas, the average kinetic energy of the particles and the temperature (in Kelvin) are directly proportional, according to the equation:

where

Ek is the average kinetic energy

k is the Boltzmann constant

T is the absolute temperature

n is the number of degrees of freedom of the molecules in the gas (n=3 for monoatomic gases, n=5 for di-atomic gases, etc..)

Therefore, as the temperature of a gas increases, the average kinetic energy of the molecules increases proportionaly to it.
