The piston of an internal combustion engine compresses 573 mL of gas.

Question

The final pressure is 15 times greater than the initial pressure. What is the final volume of the gas, assuming constant temperature? Answer in units of mL.

Answer 1

At constant T, PV = constant = P₁ (573 mL) = (15 P₁) V₂, so V₂ = 573/15 = 38.2 mL.
