What is the initial pressure of a gas in balloon that has a volume of 14.0 L and a temperature of 36°C when it was moved into a location with a pressure of 5.0 atm, 6.0 L and 18.0 °C?

Answer 1

To find the initial pressure of the gas you use The general gas equation: PiVi/Ti=P₂V₂/T₂

By making Pi(intial pressure) the subject of formula you get:Pi=P2V2Ti/ViT2

Pi=(5.0atm)(6.0L)(309.15K)/(14L)(291.15K)=2.27atm
