Thc chambcr 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 P and temperature T. The seal between the two sides is then opened 2V Otheexpertta.com × 50% Part (a) If the temperature decreases by a factor of 2 while the gas fills the chamber, give an expression for the new pressure P, in terms of the original pressure P.

The temperature of the left side is then doubled, back to the original temperature T. What is the pressure in the left side of the chamber now, in terms of the original pressure?Explanation / Answer
P1 = P
V1 = 2V
T1 = T
V2 = 3V
T2 = T/2
P2 = ?
so P1V1 / T1= P2V2 / T2
P x 2V / T= P2 x 3V / (T/2)
P x 2V / T= P2 x 6V / (T)
P2 = P/3
