Vaporization (evaporation) of water to a gas is caused by heating the water.
The change of state when water is evaporated is from liquid to gas. Evaporation is a phase transition from the liquid phase to the gas phase.
Water changes from a liquid phase to a gaseous phase when it is boiled.
When ice melts and becomes water, that is a phase change. Same when water boils and becomes steam (a gas) that is also a phase change.
When water transitions from a liquid to a gas (vapor), this phase change is known as evaporation. This occurs when the water particles gain enough energy to overcome the intermolecular forces holding them together, allowing them to spread out and become a gas.
The phase of water changes in response to temperature and pressure. When water is heated, it changes from a solid (ice) to a liquid (water) at its melting point, and then to a gas (steam) at its boiling point. Conversely, when water cools down, it transitions from a gas to a liquid to a solid.
Frost is a phase change of a gas to a solid (deposition). Water vapor turns directly to ice.

The Phase Change is complete, e.g water melting from ice phase to liquid phase or water evaporating from liquid to gas. Save
Water boiling to become steam is an example of a liquid to gas phase change.
This a phase change, from liquid to gas.
The change of water from a liquid to a gas is called evaporation. This process occurs when water molecules gain enough energy to break free from the liquid phase and enter the gas phase.
These are phase changes, ice melts into water and water evaporates into a gas.
