1. The melting point is the temperature at which a solid changes into a liquid.
2. The boiling point is the temperature at which a liquid turns rapidly into a gas.
3. The freezing point is the temperature at which a liquid becomes a solid.
4. Condensation is the process by which a gas or vapour changes into a liquid or a solid.
5. Sublimation is the process by which a solid changes directly into a gas without going through the liquid state.
6. Evaporation is the process by which a liquid changes into a vapour at any temperature below its boiling point.
7. Diffusion is the mixing process in gases or solutions due to the random motion of particles.
