When 1.5 kg of an ideal gas (specific heat at constant volume 0.8216 kJ kg K ) is heated = × at constant volume to a final temperature of 425°C, the total entropy increase is 0.4386 kJ/K. The initial temperature of the gas is most nearly. Take the antilogarithm of both sides and solve for T1 . Answer is (C). 7.
