used for welding is stored under compressed conditions with an initial pressure of 1.0 N / mm and a temperature of 240 ° C. The final pressure is twice the initial pressure and the exit temperature of the gas is 840 ° C. The heat capacity of the gas is given by. Cp = 6.7 + 0.0546 x 10^2T + 0.032 x 10 - ^5T^2 where T is in K and Cp is in J / mol. Assume the gas to behave as an ideal gas. (1) Calculate the change in entropy of the gas (J / mol K). 2.Calculate the change in entropy of the gas (J / mol K) when the final pressure is increased to 12 N / mm2. 3. Based on change in entropy in part (1), comment on the nature of the process.

Question
In a metallurgical industry, acetylene gas used for welding is stored under compressed conditions with an initial pressure of 1.0 N / mm and a temperature of 240 ° C. The final pressure is twice the initial pressure and the exit temperature of the gas is 840 ° C. The heat capacity of the gas is given by. Cp = 6.7 + 0.0546 x 10^2T + 0.032 x 10 - ^5T^2 where T is in K and Cp is in J / mol. Assume the gas to behave as an ideal gas.
(1) Calculate the change in entropy of the gas (J / mol K).
2.Calculate the change in entropy of the gas (J / mol K) when the final pressure is increased to 12 N / mm2.
3. Based on change in entropy in part (1), comment on the nature of the process.
