A sturdy, sealed container contains 0.2 moles of helium gas. Itis initially sitting in a room at 20 °C, and the pressure of thegas is observed to be 200 kPa. The container is then placed inboiling water.
(a) What will thepressure be when the temperature of the gas reachesequilibrium?
(b) What is the changein entropy of the gas during this process?
(c) Is work done on orby the gas? If so, how much?
(d) It heattransferred to or from the gas? If so, how much?
