by evaporation
The change from water vapor to liquid water is called condensation.
Evaporation is the part in the water cycle that water vapor is brought by.
When water turns into water vapor it goes through a phase change. The water uses all the energy gained not to increase heat, but turn into a gas. The name for this phase change is evaporation, or vaporization.
No, this is definitely a physical change, absolutely not a chemical.
When water changes to water vapor, it has changed its state from liquid to vapor and no chemical change has taken place. It's only a physical change.
Water Vapor
evaporation
Water vapor is in the gaseous state.
Water is changed to vapor by a physical change called evaporation :)
Water vapor condensing on a cold window is a physical change. It is simply a change in state from a gas (water vapor) to a liquid (water) due to the temperature difference. No new substances are formed during this process.
heat will change it
This is a physical change. When water vapor in the air condenses to form clouds, it is a change in state from a gas (water vapor) to a liquid (water droplets). No new substances are formed.
