It changes state at 0 degree(freezing point), which forms ice, and 100 degree(boiling point), where it turns into vapour. Chemists are trying to create 'ultra pure water', which has almost no foreign substance in it exept H2 and o, and it will freeze at 40 degree celcius!
Yes
condensation
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.
Evaporation
yes! exactly.
When water boils it changes from a liquid state to a gaseous state.
The only changes of state in pure boiling water is from liquid to gas.
The density changes.
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
It changes to gaseous state
ice
Faith
A phasechange is occured in water molecules, from liquid state to gaseous state.
No it is the temperature at which water changes physical state from a liquid to a solid.
condensation
Yes
sure
