When a piston is pushed down in a cylinder, the pressure on the gas in the cylinder increases from 125 kPa to 375 kPa. The inital volume is 3.3 L. What is the final volume?

Answer 1

Use Boyle's Law:

P₁V₁ = P₂V₂

We want the final volume, so solve for V₂:

V₂ = (P₁V₁) / P₂ = (125kPa * 3.3L) / 375kPa = 1.1 L
