its always a liquid it is just in different forms
the change of a liquid ie, water to vapor is evaporation.
When the water gets supper hot it can change to water vapor.
Liquid water can change in vapors by boiling or evaporation.
By heating it.
The change from water vapor to liquid water is called condensation.
When water vapor turns to liquid it is called condensation and is a physical change.
heat will change it
When the concentration of the liquid (water) and gas (vapor) phases do not change.
When water vapor loses energy it "turns" into a liquid
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.
You can you change liquid water into a solid (ice) by lowering its temperature. You can you change liquid water into a gas (water vapor) by raising its temperature.
