Question

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:

Answer:

B

Solution:

Total translational kinetic energy $= \frac{3}{2} n RT = \frac{3}{2} P V = 1.5 P V$ $∴$ Correct option is (b).

TestHub · Accepted Answer

Total translational kinetic energy = 2 3 ​ n RT = 2 3 ​ P V = 1.5 P V ∴ Correct option is (b).
