A. P1, V1, T1, P2, and V2: 3.5 atm, 3.2 L, 323 K, 1.5 atm, and 2.6 L, respectively
B. The problem is asking you to determine T2, the temperature of the gas based on the conditions above
C. Since pressure, volume, and temperature are all changing and are all interrelated, the combined gas law is best for this problem:
P1 • V1 P2 • V2
———— = ————
T1 T2
D. Substituting in all of the values above:
(3.5)(3.2) (1.5)(2.6)
————— = —————
(323) T2
(11.2) (3.9)
——— = ———
(323) T2
(3.9)
0.03467 = ———
T2
(3.9)
T2 = ————— = 112.49 K
0.03467
The second temperature under these conditions would be about 112.49 K.
Hope this helps!
