Question
Does the temperature of a body depend on the frame from which it is observed?

Answer

No, the temperature of a body is not dependent on the frame from which it is observed. This is because atoms/ molecules of matter move or vibrate in all possible directions. Increase in velocity at a particular direction of the container/ matter does not increase or decrease the overall velocity of the molecules/ atoms because of the random collisions the entities suffer. So, there is no net rise in temperature of the system.
