Question

Assertion: The total translational kinetic energy of all the molecules of one mole 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.

Assertion: Air pressure in a car tyre increases during driving. Reason: Absolute zero temperature is not zero energy temperature.

If the mass of each gas molecule is doubled but temperature remains constant, what happens to the average kinetic energy?

Explain the process of evaporation and analyze how it leads to cooling, using the concept of kinetic energy of molecules.
