Question

A gas initially at pressure of 250KPa and 67L. What would be the final pressure if the volume change at 45L. Name the law used.

Answer 1

Since not values are given for temperature, we assume T is constant, and we use Boyle's Law

P1V1 = P2V2

Solving for P2 we have...

P2 = P1V1 / V2

P2 = (250 kPa)(67 L) / (45 L)

P2 = 372 kPa
