MHT CET 2024 Physics question
One mole of an ideal gas at initial temperature of 'T' K does '6R' of work adiabatically. If the ratio of specific heats of this gas at constant pressure and at constant volume is , the final temperature of gas will be (R = 8.31 J moleK)
Answer: (D)
Solution
For an adiabatic process, , so the work done by the gas equals the decrease in internal energy: . For , . With and : , so
