Please read the following table in Markdown format and then answer the question according to the table. Table cells in one row are seperated by '|', and different rows are seperated by '
'.

Table:
| PHASE CHANGE |  | INITIAL PHASE |  | FINAL PHASE |  | HEAT TRANSFER |
| --- | --- | --- | --- | --- | --- | --- |
| Melting | causes a | solid | to change into a | liquid | by | adding heat; increasing temperature |
| Vaporizing; Boiling; Evaporation; Vaporization; Evaporating | causes a | liquid | to change into a | gas | by | adding heat; increasing temperature |
| Sublimating; Sublimation | causes a | solid | to change into a | gas | by | adding heat; increasing temperature |
| Freezing | causes a | liquid | to change into a | solid | by | removing heat; decreasing temperature |
| Deposition | causes a | gas | to change into a | solid | by | removing heat; decreasing temperature |
| Condensing; Condensation | causes a | gas | to change into a | liquid | by | removing heat; decreasing temperature |
