Consider a rigid, insulated box containing 0.400 mol of He(g) at 30.0°C and 1.00 atm in one compartment and 0.600 mol of N2(g) at 100.0°C and 2.00 atm in the other compartment. These compartments are connected by a partition that transmits heat. What is the final temperature in the box at thermal equilibrium?
