Answer:

D. Temperature

Explanation:

The temperature of a substance is directly proportional to the average kinetic energy of the particles in the substance according to the equation (valid for monoatomic gases)

[tex]E_K = \frac{3}{2}kT[/tex]

where

Ek is the average kinetic energy

k is the Boltzmann's constant

T is the temperature

From the equation, we see that the temperarure is directly proportional to the average kinetic energy, so the correct answer is

D. temperature
