The pressure of a gas is proportional to

The pressure of a gas is proportional to
  1. The sum of kinetic and potential energies

  2. Potential energy

  3. Kinetic energy
  4. None of the above

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.
