A horizontal cylinder 0.457 m long is divided into two parts, A and B (see Figure P 3.5) by a latched piston. As illustrated, the volume of A is twice that of B and contains helium at 311K and 10.13 bar. B contains hydrogen at 311 K and 1.01 bar. Both of these gases may be considered ideal with constant heat capacities as follows: C, (helium) = 12.56 J/mol K, and C,, (hydrogen) = 20.9 J/mol K. Heat sink A B Figure P3.5 Provision has also been made to connect volume A to a constant temperature reservoir at 311 K. When the latch is removed, the piston is allowed to seek an equilibrium position so that there are equal pressures on each side. Without neglecting friction but assuming no heat transfer to the cylinder walls, compute the final position of the piston and the temperature and pressure in both A and B for the following four cases: No contact of volume A with the 311 K reservoir: 1. Piston is diathermal 2. Piston is adiabatic Volume A is in diathermal contact with the 311 K reservoir: 3. Piston is diathermal 4. Piston is adiabatic
