Question

(a) A piston at 9.4 atm contains a gas that occupies a volume of 3.5 L. What pressure would have to be placed on the piston to force the volume to adjust to 0.84 L? atm (b) A piston at 110.0°C contains a gas that occupies a volume of 2.5 L. To what temperature would the gas have to be heated to increase the volume to 5 L at constant pressure? OC (c) A piston at 895 torr contains a gas that occupies a volume of 4.7 L. What pressure would have to be placed on the piston to force the volume to adjust to 0.32 L? atm

Explanation / Answer

1. Applying P1V1= P2V2

We have P1= 9.4 atm, V1=3.5 L, V2=0.84 L.

So we get P2 = 39.167 atm.

2. Applying V1/T1=V2/T2

We have V1= 2.5 L, T1= 110°C, V2= 5 L.

So we get T2 = 220°C.

3. Applying same P1V1= P2V2

We get P2 = 13145.3125 torr

In atm we get P2 = 17.296 atm.
