What Determines the Average Kinetic Energy of Ideal Gas Molecules?

[Linzy]

Homework Statement

Average Kinetic Energy of the ideal gas molecules inside a container, which is kept at temperature T, depends on __________________.

a) the mass of the molecules
b) the volume of hte molecule
c)the density of the molecule
d)the temperature T of the container

Homework Equations

The Attempt at a Solution

I would choose D. The only thing that I can find relates to temperature, my professor didn't cover this section very well and I'm not positive about my answer. Thank you very much!

You're right. Temperature is a measure of kinetic energy...

$$E_k=\frac{3k}{2}T$$.
