    A): Number of air molecules in a room in winter is more than the number of molecules in the same room in summer. (R) : At a given pressure and volume, the number of molecules of a given mass of a gas is inversely proportional to the absolute temperture.

    (A): Pressure of the gas increases with the decrease in volume at constant temperature (R): Number of molecules per unit volume increases with decrease in volume consequently number of collisions on the wall increases

    (A): 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. (R): The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.
