Answer :
Answer:Temperature
Explanation:
Average kinetic energy of a system of particles is given by [tex]\frac{f}{2} kT[/tex].
where,
[tex]f[/tex] is the number of degrees of freedom of the particles.
[tex]k[/tex] is the boltzmann constant.
[tex]T[/tex] is the temperature.
For general gases,
[tex]f=3[/tex]
For a given degrees of freedom,average kinetic energy is directly proportional to temperature.
So,the average kinetic energy depends on temperature.
