Pressure of ideal gas at constant volume is proportional to

Options

  1. Aforce between the molecules
  2. Baverage potential energy of the molecules
  3. Ctotal energy of the gas
  4. Daverage kinetic energy of the molecules

Correct answer

D. average kinetic energy of the molecules

Step-by-step solution

Gay Lussac's law states that the pressure of a fixed mass of a gas at constant volume is directly proportional to the temperature. i.e. p T or p 1 2 K_B T Since kinetic energy of the molecules is directly proportional to the temperature.
