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
The can collapses and closes in on itself.
It bubbles up dummy.
what happens to water molecules when they are heated
Its molecules become heated.
They melt..> they melt and turn back to water.
It evaporates
When a hydrate is heated, the water, h20 is evaporated, leaving only the anhydrous salt. If you add water to a anhydrous salt, it will transition back into a hydrate.
