The state of matter changes because it absorbs or releases heat. Here is the classification of changing state of matter based on its heat.
| Heated | Cooled |
|---|---|
| Evaporation | condensation |
| Melting | Freezing |
| Sublimation | Deposition |
Phenomena which happen because of changing state of matter
- The outside of a glass of ice tea is wet because the gas outside the glass is cooled to be liquid. It condensation.
- There is ice stuck to the wall of the freezer due to the condensation process which changes the gas into liquid then the liquid is changed into solid (ice) by freezing.
