A 0.75mol sample of argon gas is held in a rigid, thermally insulated container at an initial temperature of 290K. A heater supplies 1.1×103J of energy to the gas. Assuming argon behaves as an ideal monatomic gas and no work is done, what is the final temperature T2 of the gas? (Take R=8.31J/molK.)
(a) 380K
(b) 470K
(c) 410K
(d) 360K
