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

Answer:

$P_2=20.5$

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

$P_1=8.2 \times 10^4$

$P_2=?$

$V_1=15L$

$V_2=6.00 \times 10^4L$

from the first equation after putting all the value

we get,

$P_2=20.5$
