The average kinetic energy of a molecule of the gas is

Options

  1. Aproportional to absolute temperature
  2. Bproportional to volume
  3. Cproportional to pressure
  4. Ddependent on the nature of the gas

Correct answer

A. proportional to absolute temperature

Step-by-step solution

The average kinetic energy of a molecule of the gas = 3 2 R T . Average kinetic energy of one molecule of gas = 3 2 k T         (   k = R N A ) Where k is Boltzmann constant and T is absolute temperature. So, from above relation we can say average kinetic energy of molecule is directly proportional to absolute temperature.
