Question

4 on the diagram

fill in the phase changes in the blank provided.
phase change
concept map
solid
liquid
gas
a condensation
b deposition
c evaporation
d sublimation

Explanation:

First, identify each phase change direction:

1. Solid → Liquid: This is melting (not listed in options, but we focus on the labeled #4 which is Gas → Solid).
2. Liquid → Solid: This is freezing.
3. Solid → Gas: This is sublimation (option d).
4. Gas → Solid: This is deposition (option b).
5. Gas → Liquid: This is condensation (option a).
6. Liquid → Gas: This is evaporation (option c).

The question references #4 on the diagram, which is the phase change from gas to solid, defined as deposition.

Answer:

b. deposition
