problem 8.36)
A) P1/T1 = P2/T2
P1 = 510 torr = 0.67 atm , T1 = 00C = 273 K
P2 = 2500 torr = 3.29 atm , T2 = ?
T2 = P2 T1 / P1
T2 = 3.29 x 273 / 0.67
T2 = 1340 K = 1067 0C
T2 = 1067 0C
B) P1/T1 = P2/T2
P1 = 740 mmHg = 0.974 atm , T1 = 500C = 323 K
P2 = 0.908 atm , T2 = ?
T2 = P2T1 / P1
T2 = 0.908 x 323 / 0.974
T2 = 301 K = 28 0C
T2 = 28 0C
problem 2 )
part A)
P1V1/T1 = P2V2/T2
P1 = 760 mmHg = 1.0 atm , V1 = 5.00 L , T1 = 200C = 293 K
P2 = 76.0 mmHg = 0.1 atm , V2 = ? T2 = -500C = 223 K
V2 = P1V1T2 /T1P2
V2 = (1.0 x 5.00 x 223 / 293 x 0.1)
V2 = 1115 / 29.3
V2 = 38.0 L
