Explain why
(a) Two bodies at different temperature `T_(1) and T_(2)` if brought in thermal contact do not necessarily settle to the mean temperature `(T_(1)+T_(2))//2` ?
(b) The coolant in a chemical or nuclear plant (i.e., the liquid used to prevent different parts of a plant from getting too hot)should have high specific heat. Comment.
(c) Air pressure in a car tyre increases during driving . Why?
(d) The climate of a harbour town is more temperature (i.e., without extremes of heat and cold) than that of a town in a desert at the same latitude. Why?
