Gas vs. Liquid: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 16, 2023
Gas is a state of matter with no fixed shape or volume, while liquid has a fixed volume but no fixed shape, conforming to its container.

Key Differences

Gases are composed of particles that are far apart and move freely, resulting in no fixed shape or volume. Liquids have particles that are closer together than gases but still move freely, allowing them to take the shape of their container while maintaining a fixed volume.

In a gas, the particles have high kinetic energy, which leads to expansion and filling any space available. Liquid particles, while still active, have less kinetic energy compared to gases, causing them to remain more compact and giving the liquid a definite volume.

Gases can be compressed easily due to the large spaces between their particles, whereas liquids are nearly incompressible because of the limited space between particles.

The interaction between particles in a gas is minimal, which is why gases can mix easily and uniformly. In liquids, the stronger intermolecular forces result in a definite volume and surface tension.

Changes in temperature and pressure have a significant effect on gases, easily altering their volume. Liquids are relatively less responsive to temperature and pressure changes, maintaining their volume but changing in density.
