2 moles of an ideal gas absorbs 720 cal heat when heated from 27ºC to 87ºC, at constant volume. 'Cp/Cv' for the gas is :

 

Five moles of a monoatomic ideal gas is heated from 300 K to 400 K at constant pressure. The amount of heat absorbed is :

 

Calculate the amount of heat required to raise the temperature of 50 gm water from 25ºC to 55ºC. Specific heat capacity of water = 4.2 J/ºC-gm.

 

One mole of argon gas (assuming ideal behaviour) is expanded reversibly and adiabatically from 2.5 m^3 at 300K temperature to 5.0 m^3. Cv m for argon is 12.55 JK^–1mol^–1.Calculate the final temperature and pressure of the gas.

 

Two mol of an ideal gas is expanded isothermally and reversibly at 300K to twice the original volume. Calculate q, w, E, and H.
