Find the false statement for ideal gases.

Options

  1. AKinetic energy of 1 ~mol of gas depends on mass of the gas molecule.
  2. BKinetic energy increases with increase in temperature.
  3. CKinetic energy of 1 ~g of H ₂ is higher than that 8 ~g of O ₂ at the some temperature.
  4. DAt a given temperature, kinetic energy does not depend on the pressure of the gas.

Correct answer

D. At a given temperature, kinetic energy does not depend on the pressure of the gas.

Step-by-step solution

K.E. = 1 2 mv _ rms ^2 ; v _ rms = 3 KT m At a given temperature T, v_ rms 1 m K.E. of 1 mol. of gas is independent of the gas molecules.
