A 1 Liter Container A Holding 0 1 Mole Of Air At 20 C Is Attached To A Second 1 Liter Container B Holding An Additio 1 (26.64 KiB) Viewed 43 times
A 1-liter container, A, holding 0.1 mole of air at 20°C is attached to a second 1-liter container, B, holding an additional 0.1 mole of air at 100°C. The whole A-B assembly is insulated. The valve separating the containers is opened and the gases are allowed to equilibrate quasistatically. (a) (5 points) What is the equilibrium temperature (in °C)? (b) (5 points) What is the equilibrium pressure (in Pa)?
The equilibrated gas in B is now pushed by a piston quasistatically into A until chamber B is empty. The volume of container A remains constant. (5 points) What is the final temperature (in °C)? (5 points) What is the final pressure (in Pa)?
(10 points) What is the overall change in entropy, AS, of the AB system (in J/K, from the start of the problem to the end)?
