The individual atoms vibrate more rapidly because they are being fed kinetic/thermal energy from the heat which they translate into movement.
new molecules starts to form
they get exited and move faster than cold molecules
The liquid molecules are transformed in gas molecules.
The liquid molecules are transformed in gas molecules.
The magnitude of the vibration of its molecules gets increased.
they get farther apart.
what happens to water molecules when they are heated
the hot-air molecules bang on each other harder.
the hot-air molecules bang on each other harder.
The molecules in side move or spread apart
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
When a noble gas is heated, its molecules move faster (this is the same as saying that the gas heats up).
