Assertion : The total translational kinetic energy of all the molecules of a given mass of an ideal gas is 1.5 times the product of its pressure and its volume. Reason : The molecules of a gas collide with each other and the velocities of the molecules change due to collision.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

Average translational kinetic energy of a gas molecule is E= 3 2 k T For all gas molecules E= 3 2 k T N_A= 3 2 R T= 3 2 P V
