The liquid molecules are transformed in gas molecules.

Its density decreases.
what happens to water molecules when they are heated
The water molecules would speed up, but not to the point of boiling.
Its molecules become heated.
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
Heating water molecules causes them to move faster and faster. Water when cool is in a way (sticky). When heated the water molecules are moving far too quickly stick together. The heated water molecules become less dense and may stick to air molecules. Floating into and combining with the atmosphere.
100 degrees celsius
When gypsum is heated to 120o C, it tuns into plaster of paris, after loosing about 75% of its water.
the molecules evapourate
When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.
If You're suggesting what happens to water when heated then the answer is: Water molecules speed up by the heat increasing it's temperature and when it reaches 100 Degrees the molecules are so fast that the water turn into a gas (Steam) But if you are just asking about the temperature then; When you heat water the temperature also increases.
