Now the friends try a homework problem. Two identical cylinders with a mevable piston contain 0.8 mol of helium gas at a temperature of 300 K. The temperature of the gas in the first cylinder is increased to 412 K at constant volume by doing work W, and transferring energy Q₁, by heat. The temperature of the gas in the second cylinder is increased to 412 K at constant pressure by doing work W₂ while transferring energy Q₂ by heat. Find AEint, 1 Q1, and W, for the process at constant volume. AEint, 1 J J 3 9₁- W₁ = Find AEint, 2 Q2, and W₂ for the process at constant pressure. AEint, 2 3 2₂- W₂= ] J
