(i) Why does the air pressure in a car tyre during driving increase?
(ii) Why coolant used in a chemical plant should have high specific heat?
(i) The air pressure in a car tyre during driving increases because work done against friction is converted into heat. Due to which the gas in the trye gets heated, and hence, the pressure of gas increases as P α T at constant volume.
(ii) The coolant used in a chemical plant should have high specific heat because heat absorbed by a substance is directly proportional to specific heat of the substance.
