Answer:
Therefore the volume of the gas is 32 cubic feet.
Step-by-step explanation:
Given that,
The volume of a gas varies directly with its temperature and inversely with the pressure.

V= Volume of the gas at constant mass
T= Temperature at constant mass
P= pressure at constant mass

.
Given that,
At constant mass, the volume of a certain gas is 15 cubic feet and a pressure of 40 pound per square inch at a temperature 300 k.
=15 cubic feet,
=40 pound per square inch and
= 300 K
,
=20 pound per square inch and
= 320k
.
Plugging all values


cubic feet
Therefore the volume of the gas is 32 cubic feet.
