A quantity of gas (mean molecular weight 36.2) is compressed according to the law pvn = constant, the initial pressure and volume being 1.03 bar and 0.98 m³ respectively. The temperature at the start of compression is 17°C and at the end it is 115°C. The amount of heat rejected during compression is 3.78 kJ, cp = 0.92. Calculate :(i) Value of n, (ii) Final pressure, (iii) Change in entropy.
