A heat enegine works on a carnot cycle with a heat sink at a temperature of 2700K . The efficiency of the engine 10% . Determine the temperature of heat source.

One mole of an ideal monatomic gas requires 210 J heat to raise the temperature by 10 K , when heated at constant temperature. If the same gas is heated at constant volume to raise the temperature by 10 K then heat required is

50 gm of copper is heated to increase its temperature by 10^(@)C. If the same quantity of heat is given to 10 gm of water, the rise in its temperature is (Specific heat of copper =420 Joule-kg^(-1)@C^(-1)

50 g of copper is heated to increase its temperature by 10^@C . If the same quantity of heat is given to 10g of water, the rise in its temperature is (specific heat of copper =420J//kg^(@)//C )
