A beaker with a metal bottom is filled with 20g of water at 20∘C. It is brought into good thermal contact with a 4000cm3 container holding 0.40mol of a monatomic gas at 10atm pressure. Both containers are well insulated from their surroundings.
What is the gas pressure after a long time has elapsed in atm? You can assume that the containers themselves are nearly massless and do not affect the outcome
Two canisters A and B each contain 0.20 mol of a diatomic gas at 400 K and a pressure of 405300 Pa.
