Statement I 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. Statement II The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.

Options

AStatement I is true, Statement II is true; Statement II is a correct explanation for Statement I
BStatement I is true, Statement II is true; Statement II is NOT a correct explanation for Statement I
CStatement I is true, Statement II is false
DStatement I is false, Statement II is true

Correct answer

B. Statement I is true, Statement II is true; Statement II is NOT a correct explanation for Statement I

Step-by-step solution

Total translational kinetic energy

=\frac{3}{2} n R T=\frac{3}{2} P V=1.5 P \mathrm{~V}

\therefore

Correct option is (b).
