Explanation

Gas: No definite shape or volume – Expands to fill any container.

Example: Oxygen, CO₂.

Solid: Fixed shape and volume (e.g., iron).

Liquid: Fixed volume, no fixed shape (e.g., water).

Explanation

In solids, heat transfer occurs primarily through conduction, where vibrations and collisions of particles (atoms or molecules) transfer energy from one point to another.
