The physical state change from liquid to gas usually occurs at boiling. However water can evaporate at room temperature. Evaporation is not boiling, it is a process by which surface molecules of water are escaping into the air.

Water does not necessarily have to boil to evaporate. Evaporation can occur at any temperature, even below the boiling point of water. While boiling is a rapid form of evaporation that happens at the boiling point, evaporation can happen at a slower rate at lower temperatures.

What will happen to the water when the temperature rises?
It will boil and eventually evaporate.
What will you get if you boil salt water?
If you boil it, the water will evaporate. If you leave it boiling long enough, you should only have salt left.
What will happen when water boils for 2 hours.?
If you continue to boil water for 2 hours, or any extended length of time, it will evaporate, i.e. turn to steam (water vapor). Depending on how much water you have to begin with, and how long it let it boil, it could all evaporate, or only some will evaporate.
How can you change the states of water?
boil it, freeze it or leave it in a jar to evaporate
Will water with salt evaporate faster than water without salt experiment?
Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well
A way to show that sea water is not a pure substance?
Boil it. The water will evaporate, leaving salt at the bottom of the pot, which did not evaporate and was left behind.
Why does salt water evaporate slower than regular water?
salt water evaporates slower than regular water because the salt makes it harder to boil and evaporate
What is the state of water at 257c?
There isn´t water at 257c because the water was starting to boil and to evaporate at 100c.
What are the materials for rock candy?
sugar and water......boil sugar and water drop in a string let evaporate
Is it true if you boil saltwater it becomes fresh water?
The water would evaporate, leaving the salt behind.
When will a liquid evaporate and when it boil?
what is it
WHAT WOULD HAPPEN IF YOU MICROWAVE WATER?
It'll warm up, start to boil and eventually evaporate.
