The pressure of a gas is proportional to

Options

  1. AThe sum of kinetic and potential energies
  2. BPotential energy
  3. CKinetic energy
  4. DNone of the above

Correct answer

C. Kinetic energy

Step-by-step solution

The force exerted by gas molecules per unit area is the pressure, the gas molecules will exert more force if they have more kinetic energy and the rate of the number of collisions of gas molecules per unit area will increase the momentum transfer which again leads to increase in kinetic energy. Therefore, pressure is directly proportional to the kinetic energy of gas molecules.
