The pressure, P, of a gas varies inversely with its volume, V. Pressure is measured in units of Pa. Suppose that a particular amount of a gas is initially at a pressure of 84 Pa at a volume of 36 L. If the volume is expanded to 216 L, what will the new pressure be?

a) 6 Pa
b) 14 Pa
c) 216 Pa
d) 504 Pa <---- Right?

1 answer

NO!! If the volume goes up the pressure goes down

P1 V1 = P2 V2
84 * 36 = P2 * 216
