Understanding Phase Changes
Phase changes refer to the transitions between solid, liquid, and gas states of matter. These changes occur due to the addition or removal of heat energy and can be classified into several categories:
Types of Phase Changes
1. Melting: The process where a solid turns into a liquid when heat is applied.
2. Freezing: The transformation of a liquid into a solid as heat is removed.
3. Vaporization: The change from liquid to gas, which occurs through boiling or evaporation.
4. Condensation: The conversion of gas back into liquid when it cools down.
5. Sublimation: The transition from a solid directly to a gas without passing through the liquid phase (e.g., dry ice).
6. Deposition: The process where gas transforms directly into a solid without becoming a liquid first.
