The chamber has a seal which separates the right from the left half. The chamber is sealed and an ideal gas is pumped into the right side at a pressure P and temperature T. The seal between the two sides is then opened. a If the temperature in the chamber is decreased by a factor of 2 by a refrigeration system while the gas fills the chamber, give an expression for the new pressure P' in terms of the original pressure P. b) The chamber is then sealed again, trapping 2/3 of the gas molecules in the left side. The temperature of the left side is then doubled by a heater, back to the original temperature T. What is the pressure in the left side of the chamber now, in terms of the original pressure?
