Name different changes of state.

Sure, here are the different changes of state:

1. Melting: This is the change from a solid state to a liquid state. It occurs when heat is applied to a solid, increasing its temperature to the point where the solid's particles have enough energy to break free from their fixed positions.

2. Freezing: This is the change from a liquid state to a solid state. It occurs when a liquid is cooled, decreasing its temperature to the point where the liquid's particles do not have enough energy to move freely and instead form a rigid structure.

3. Vaporization: This is the change from a liquid state to a gas state. It can occur through either evaporation (at the surface of the liquid) or boiling (throughout the liquid).

4. Condensation: This is the change from a gas state to a liquid state. It occurs when a gas is cooled, decreasing its temperature to the point where the gas's particles do not have enough energy to move freely and instead form a liquid.

5. Sublimation: This is the change from a solid state directly to a gas state, bypassing the liquid state. It occurs when a solid is heated and its particles have enough energy to transition directly into a gas.

6. Deposition: This is the change from a gas state directly to a solid state, bypassing the liquid state. It occurs when a gas is cooled and its particles do not have enough energy to remain as a gas, transitioning directly into a solid.
