Consider a rigid, insulated box containing 0.400 mole of He(g) at 29.4°C and 1.00 atm in one compartment and 0.600 mole of N,(g) at 53.9°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?

Question
Consider a rigid, insulated box containing 0.400 mole of He(g) at 29.4°C and 1.00 atm
in one compartment and 0.600 mole of N,(g) at 53.9°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? [For He(g), C, = 12.5 J
K mol-l; for N2(g), C, = 20.7 J K-l mol-1.]
