P1V1/T1 = P2V2/T2
T1 = T2
P1V1 = P2V2
V2 = P1V1/P2
V2 = 2200*1.55/14.70 = 231.97 ft3
Solution: The gas will occupy 231.97 square feet if the typical A1 hydrogen gas cylinder has 1.55 cubic feet of gas that is compressed at 2,200 pounds per square inch at the same temperature and normal atmospheric pressure.
15°F = 263.7 K
25°C = 298.2 K
V1/T1 = V2/T2
V2 = T2V1/T1
V2 = 298.2*15/263.7 = 16.96 liters
Solution: The new air volume will be 16.96 liters if a 15-liter air sampling bag is filled at 15°F ambient temperature and reverted to 25°C under constant pressure.
32°F = 273 K
P1V1/T1 = P12V1/T2
1/T1 = 2/T2
T2 = 2T1
T2 = 546 K
Solution: The temperature must be 546 K in order to double the 1 cubic meter volume that is occupied by a gas at a temperature of 32°F.
P1V1 = P2V2
P2 = 1.05P1
P1V1 = 1.05P1V2
V1 = 1.05V2
V2 = V1/1.05
V2 = 1/1.05 = 0.95 m3
Solution: At this point, a gas that occupies 1 cubic meter at a pressure of 1 atmosphere will occupy 0.95 liters with an increase of 5% in atmospheric pressure.
110°F = 316....
