Question

1m3 of an ideal gas at 500 K and 1000 kPa expands reversibly to 5 times its initial volume in an insulated container. If the specific heat capacity (at constant pressure) of the gas is 21 J/mole.K, the final temperature…

Accepted Answer

Option B. 174 K. Answer & Solution Answer: Option B Solution: Insulated cylinder adiabatic system & PV^ = CONSTANT & TV^ - 1 = CONSTANT & T_1T_2 = V_2^ - 1V_1 & 500T_2 = ( 5 )^ - 1 & C_P - C_V = R ( For ideal gas ) & = 1.65 & So, T_2 = 176.05\,K
