Ideal Gas Model, Quasi-Static Processes

The Bermuda Triangle A cylinder with initial volume V contains a sample of gas at pressure p. The gas is heated in such a way that its pressure is directly proportional to its volume. After the gas reaches the volume 3V and pressure 3p, it is cooled isobarically to its original volume V. The gas is then cooled isochorically ...continues

Water, Monatomic Gas Problem - Calculate Gas Pressure after Prolonged Contact

A beaker with a metal bottom is filled with 20 g of water at 20 degrees Celsius. It is brought into good thermal contact with a 4000 cm3 container holding 0.40 mol of a monatomic gas at 10 atm pressure. Both containers are well insulated from their surroundings. Question: What is the gas pressure after a long time has elapsed? ...continues
