Question

label the diagram below. phase change diagram 9.kinetic energy 10.particles 11.heat is a solid b c liquid d e gas temperature heat energy word bank melting freezing condensation evaporation decreases speed up slow down increases added taken away unit 3 test go 35

Explanation:

The phase - change from solid to liquid is melting (at B), heat is added during this process. From liquid to gas is evaporation (at D), heat is also added. When going from gas to liquid is condensation, heat is taken away. When going from liquid to solid is freezing, heat is taken away. Kinetic energy increases when heat is added and particles speed up, and decreases when heat is taken away and particles slow down.

Answer:

1. Speed up
2. added
3. increases
4. Speed up
5. added

B: melting
D: evaporation
