Consider a cylinder containing 2 mol of an ideal gas at an initial temperature of 25 C. The cylinder is fitted with a piston on which a weight is placed, subjecting the gas to a constant pressure of 2.66 atm. The cylidner is then wrapped with a heater, from which 1.50 kJ of heat is absorbed by the gas, forcing the piston to move upwards under constant pressure.

What is the final temperature of the gas?
