Firstly, there are two hydrogen molecules and one oxygen molecule that make up water. These hydrogen molecules are bound by hydrogen bonds to the oxygen molecule. Hence the meaning of H20. 2 hydrogens and 1 oxygen.
The hydrogen molecules that are bound to the oxygen molecule are broken at high temperatures therefore water (in liquid condition) is turned into water vapor (gas condition).
Evaporates
The water gets heated up and turns into a gas
It evaporates
It boils
it will now occur evaporation
Hey there......... when water is heated the molecules of water i.e. Hydrogen and oxygen gets heated and get lite and forms vapour which is carried on by air
The can collapses and closes in on itself.
It bubbles up dummy.
what happens to water molecules when they are heated
The volume increase.
Its molecules become heated.
i believe when water vapor is heated it just ...poof! goes away! but i could be wrong imm only in high school.
