1. (17 pts) Ideal gases are occupied in compartment A and compartment B in the condition below (left). Two compartments are separated by a movable adiabatic wall, which does not flow heat and molecules. When only compartment A is heated to reach four times higher than the initial temperature, the wall moves to a certain point and stop. (note that there is no stopper in this case) What is the final volume of compartment A and the final pressure of compartment B after reaching the equilibrium? You can assume that there is no friction between the walls as it moves. The illustration below is not scaled. (Note: to clarify, since walls are insulated, only compartment A can be heated to increase temperature without affecting the temperature of the compartment B as illustrated below). If necessary, use R=8.314JK1mol1
