A body of mass 750 g requires 13,500 J of heat eneragy in order to raise its temperature from 25^@C to 55^@C . Calculat its specific heat capacity.

One mole of an ideal gas requires 207 J heat to rise the temperature by 10 K when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by the same 10 K , the heat required is (Given the gas constant, R = 8.3 J/mol-K).

An energy of 84000 J is required to raise the temperature of 2 kg of water from 60^@ C " to " 70^@ C . Calculate the specific heat capacity of water.

A ball is dropped on a floor from a height of 2.0m After the collision it rises up to a height of 1.5m . Assume that 40% of the mechanical energy lost goes as thermal energy into the ball. Calculate the rise in the temperature of the ball in the collision specific heat capacity of the ball is 800J kg^(-1) K^(-1)
