  Question 9 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. Question 10 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. Question 11 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. Question 12 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. Question 13 110°F = 316....
