Wat a tem AN -- Due Date: 1131/2020 11.00 TIM I Date: 73112020 TTY:00 PM (9%) Problem 1: Consider the two-sided chamber shown, where the right side has a volume of V and the left side has a volume of 2V. The chamber has a scal 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 Pand temperature T. The seal between the two sides is then opened. 2V > Otheexpertta 50% Part (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.
