Question

The average kinetic energy of molecules of a gas is directly related to which physical quantity?

पर्याय

• Pressure

• Volume

• Absolute temperature

• Density

Answer 1

Absolute temperature

Explanation:

According E_k = \[\frac {3}{2}\]k_BT, the average kinetic energy of gas molecules is directly proportional to the absolute temperature T (in Kelvin). As the temperature increases, the kinetic energy of particles increases.
