Statement-1: The total translational kenetic energy of fall the molecules of a given mass of an ideal gas is 1.5 times the product of its pressure and its volume because.
Statement-2: The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.

Options

A. Statement-1 is True,Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement--1
C. Statement-1 is True, Statement-2 is False
D. Stement-2 is False, Statement-2 is True

Answer

B

Explanation

(b) Statement 1: The total kinetic energy of n moles of gas
is `K=3/2nRT`
But `PV=nRT`
`:. K=1.5 PV`
Statement one is true.
Statement-2: The molecules of a gas collide with each
other and the velocities of the molecules change due
to collision.
But statement 2 is not a correct explanation of
statement-1.
