Question

a 15.0 L tank of gas is contained at a high pressure of 8.20*10^4. The tank is opened and the gas expands into an empty chamber with a volume of 6.00*10^4 L. Calculate the new pressure of the gas.

Answer 1

`P_2=20.5`

Step-by-step explanation:

Assuming that temperature is constant

According to Boyle's Law, at constant temperature pressure is inversly proportional to the volume and mathematically it can be expressed as:

`P_1V_1 = P_2V_2`..........1

`P_1=8.2 * 10^4`

`P_2=?`

`V_1=15L`

`V_2=6.00 * 10^4L`

from the first equation after putting all the value

we get,

`P_2=20.5`
