1.36 km
B)
2.16 km
C)
1.85 km
D)
2.45 km
E)

Two identical containers, A and B, hold equal amounts of the same ideal gas at the same Po, Vo and To. The pressure of A then decreases by a half while its volume doubles; the pressure of B doubles while its volume decreases by a half. Which statement correctly describes the temperatures of the gases after the changes?
a. TA = 0.5TB = To. b. TB = 0.5TA = To. c. TB = TA = To. d. TA = 2TB = To. e. TB = 2TA = To.
