Consider a sample of a gas in a cylinder with a movable piston.

Show diagrammatically the changes in the position of the piston, if the temperature is decreased from 400 K to 300 K, and pressure is decreased from 4 bar to 3 bar.

Solution

According to combined gas law,

`("P"_1"V"_1)/("T"_1)=("P"_2"V"_2)/("T"_2)`

∴ `(4xx1)/400=(3xx"V"_2)/300` .....[Assuming V1 = 1 L]

∴ V2 = 1 L

Thus, the volume of the gas remains the same.

Hence, there will be no change in the position of the piston.
