Question

15L tank of gas is contained at a high pressure of 8.20 •10 ^4 torr. The tank is opened and the gas expands into an empty chamber with a volume of 6• 10^4 L

Answer 1

The question is incomplete. The complete question is:

15L tank of gas is contained at a high pressure of
`8.20* 10^4 torr`. The tank is opened and the gas expands into an empty chamber with a volume of

where,

`P_1\text{ and }V_1` are initial pressure and volume.

`P_2\text{ and }V_2` are final pressure and volume.

We are given:

`P_1=8.20* 10^4torr\\V_1=15L\\P_2=?\\V_2=6* 10^4L`

Putting values in above equation, we get:

`8.20* 10^4* 15L=P_2* 6* 10^4L\\\\P_2=20.5torr`

Thus new pressure will be
`20.5torr`
