A sample of a gas at 0.5 atm pressure and 25 OC occupies a volume of 2.0 L. What pressure is necessary to cause the gas to occupy 0.5 L at same temperature?

Answer 1

This is a problem where you are given an initial pressure (P1), temperature (T1) and volume (V1) of a gas. You are also provided with a final volume (V2) of that gas at the same temperature, and asked to find the final pressure (P2).  Since the temperature is constant, we can use Boyle's Law:  P₁V₁ = P₂V₂.

(0.5 atm)(2.0 L) = (P₂)(0.5 L)

P₂ = 2 atm
