Question

What determines the average kinetic energy of the molecules of any gas?

Answer 1

Answer: temperature

Explanation:

Kinetic energy is the energy possessed by an object by virtue of its motion.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:  

$K=\frac{3RT}{2}$

K= kinetic energy

R= gas constant

T= temperature  

From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if temperature is more, average kinetic energy of the system is more.

Answer 2

Temperature does. :)
