Question

When we place a gas cylinder on a van and the van moves, does the kinetic energy of the molecules increase? Does the temperature increase?

Answer 1

When we place a gas cylinder on a van and the van moves, the kinetic energy of the molecules  will not increase and the temperature will increase.

Explanation:

• If we put a gas cylinder on a van, and the van drives, the molecules ' kinetic energy is not increasing.

• This is because it is important to note that there is no increase in the velocity of the molecules with respect to the gas cylinder walls.

• But if the cylinder is held in a uniformly moving vehicle and the vehicle is again accelerated or decelerated, the resulting effect is that the gas kinetic energy will change and temperature will increase.
