Explanation:

* Intermolecular forces: Gases have much weaker intermolecular forces than liquids. This means that the molecules in a gas are much farther apart and have more freedom to move around.

* Kinetic energy: Gas molecules have higher kinetic energy than liquid molecules. This means they move faster and collide with each other more frequently, leading to greater expansion.

* Compressibility: Gases are highly compressible, meaning that their volume can be easily reduced by applying pressure. Liquids are less compressible.

Example:

Imagine a balloon filled with air. When you heat the air inside the balloon, the gas molecules gain kinetic energy and move faster. They collide more frequently with the walls of the balloon, causing the balloon to expand.

Conclusion:

Due to their weaker intermolecular forces, higher kinetic energy, and compressibility, gases expand significantly more than liquids when heated or subjected to changes in pressure.
