(a) A gas has a density of 1.875 kg/m3 at pressure of 1 bar and temperature of 15°C. A mass of 0.9 kg of this gas requires heat transfer of 175 kJ to raise the temperature from 15°C to 250°C www.puneqp.com [4062]-111 3 P.T.O. while pressure of the gas remains constant. Determine : (i) Characteristic gas constant (ii) Cp of gas (iii) Cv of gas (iv) Change in internal energy during the process (v) Work. [10] (b) What is throttling ? Give two examples. [3] (c) Write expression for heat, work and change in internal energy of ideal gas during constant volume process, in a close system.
