Randall D. Knight — Heat Engines and Refrigerators: Problem 70
FIGURE CP21.70 shows two insulated compartments separated by a thin wall. The left side contains 0.060 mol of helium at an initial temperature of 600 K and the right side contains 0.030 mol of helium at an initial temperature of 300 K. The compartment on the right is attached to a vertical cylinder, above which the air pressure is 1.0 atm. A 10-cm-diameter, 2.0 kg piston can slide without friction up and down the cylinder. Neither the cylinder diameter nor the volumes of the compartments are known. a. What is the final temperature? b. How much heat is transferred from the left side to the right side? c. How high is the piston lifted due to this heat transfer? d. What fraction of the heat is converted into work?
