Question 1
An ideal gas of mass 0.5 kg has a pressure of 600 kPa, a temperature of 77
and a volume of 0.08 m3. This gas undergoes an irreversible process to a final pressure of 600 kPa and final volume of 0.12 m3, during which the heat addition and work done on gas are 2 kJ and 30 kJ respectively. The value of Cv of gas is

Which of the following statements are TRUE with respect to heat and work?
(i) They are boundary phenomena
(ii) They are exact differentials
(iii) They are path functions
Question 3
In an internal combustion engine, during the compression stroke the heat rejected to the cooling water is 50 kJ/kg and the work input is 100 kJ/kg. What is the change in internal energy of the working fluid ?
Question 4
Calculate the net heat interaction (kJ) for the cycle shown in the figure.
Question 5
For a system of ideal gas, in a reversible isothermal process the heat transferred to the system is 0.75 kW. The internal energy at the initial point is 2.05 kJ/s. Determine the work done during the process.
Question 6
A closed gaseous system undergoes a reversible constant pressure process at 2 bar in which 100 kJ of heat is rejected and the volume changes from 0.2 m3 to 0.1 m3. The change in the internal energy of the system is
