Q4. An ideal gas is heated in a cylinder at constant volume from a temperature of 300 K to a temperature of 1208 K. The initial pressure and volume are 1.02 bar, 0.084 m³ respectively.

It is further heated at constant pressure to 1474 K. The gas then expands isentropically to ten times the initial volume.

The change in specific entropy for the first process is 1.0 kJ/kgK and in the second process it is 0.2 kJ/kgK.

(a) Sketch the p-V and T-s diagrams.

(b) Calculate EACH of the following:

(i) The values of C_v, C_p, and γ for the gas

(ii) The final temperature of the gas

(iii) The specific work transfer.
