#### Which of the following statements regarding a gas's volume is accurate?Option: 1 The volume of a gas is fixedOption: 2 The volume of a gas is inversely proportional to its temperatureOption: 3 The volume of a gas is variableOption: 4 A gas's volume is directly proportional to its pressure.

A gas's volume can alter depending on a variety of factors, including temperature, pressure, and the presence of particles.

Gases are extremely compressible and may expand to fill any container in which they are placed, explaining why.

The other claims, while still relevant to gas behaviour, are not totally true.

While raising a gas's temperature might result in an increase in its volume (at constant pressure), this connection is direct rather than inverse, meaning that a gas's volume is directly proportionate to its temperature (so answer c is incorrect).

The volume of a gas can also decrease when its pressure increases (while maintaining a constant temperature), and this relationship is direct, meaning that the volume of a gas is inversely proportional to its pressure.

As a result, although option d is not the greatest choice, it is somewhat right.
