It’s B Temperature and volume

Dominique Ritter · Answer 2

Given that the gas is enclosed you know that the number of moles does not change.

Assuming that the piston moves freely, you infere the pressure is constant.

The voume is evidently variable.

Temperature tends to decrease when the gases expands.

Therefore, there are two variables: the volumen and the temperature.

Answser: option 2: temperature and volume.
