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.
