Explanation

Matter can change from one form to another through various processes, including:

• Heating: Melting (solid to liquid), Vaporization (liquid to gas)
• Cooling: Freezing (liquid to solid), Condensation (gas to liquid)

For example, ice (solid) can change to water (liquid) by heating, and water (liquid) can change to steam (gas) by further heating.

Similarly, steam (gas) can change to water (liquid) by cooling, and water (liquid) can change to ice (solid) by further cooling.
