What happens to the particles in water when it boils?

Answer 1

In solids, particles vibrate and stay in a fixed position. (ice) When melting particles gain more energy and can move more rapidly, this is called the liquid state. (water) As heating further these particles gain more energy and there are now moving totally freely from each other (boiled water).

Answer 2

When water boils, the kinetic energy of the water molecules increases, causing them to break the hydrogen bonds holding them together. As a result, the water molecules escape into the air as steam, leaving behind an empty space in the liquid water.

Answer 3

I think that they start to move very rapidly, just like when water boils.

Answer 4

The particles move violently during boiling. This happens due heat of the medium.

Answer 5

The energy of molecules increase and the intermolecular bonds are broken.

Answer 6

It turns into water vapour

Answer 7

The atoms themselves have strong electrostatic forces of attraction, wheras the molecules of methane have weak intermolecular forces of attraction because they are made up of a simple molecular structur. Thus meaning when energy is applied, the methane molecules easily break apart and turn into gas.

Remember it's not the bonds between the atoms that break, but the bonds between the molecules.
