Question

1. in the diagram below, label each phase and phase change indicated. (5)

Explanation:

The first container shows a solid phase with particles closely packed. The second is a liquid phase with more - spread out particles. The third is a gas phase with highly dispersed particles. Phase - change 1 is melting (solid to liquid), phase - change 2 is freezing (liquid to solid), phase - change 3 is condensation (gas to liquid), and phase - change 4 is vaporization (liquid to gas).

Answer:

1. Melting (Solid to Liquid)
2. Liquid
3. Condensation (Gas to Liquid)
4. Vaporization (Liquid to Gas)
5. Solid
