Explain why (a) Two bodies at different temperatures T₁and T₂ if brought in thermal contact do not necessarily settle to the mean temperature (T₁ + T₂ )/2. (b) The coolant in a chemical or a nuclear plant (i.e., the liquid used to prevent the different parts of a plant from getting too hot) should have high specific heat. (c) Air pressure in a car tyre increases during driving. (d) The climate of a harbour town is more temperate than that of a town in a desert at the same latitude.
