Solid, liquid, gas (and atomic/subatomic). in that order, moving from cold to hot.
First of all, know this: There is no such thing as cold. Only heat or lack of it. Agitation of atoms = electromagnetic activity = heat.
Agitation can be caused by an external source of heat or a chemical reaction. When molecules are subjected to heat they become agitated and "vibrate". When they vibrate they bump into one another and bounce off and, subsequently, bump into another. More heat, more vigorous bumping. More vigorous bumping means they are hitting harder and thus, spacing themselves further apart exponentially and thus, an increase in volume.
H^2O is your example. Ice, water, steam. Then the breakdown of the molecule into elements.

Hi. Aren't there 4 phases? They are all related to bonding of atoms to one another. Solid, liquid, gas, plasma. Temperature shakes the bonds.

Solid: element has definite volume and shape
Liquid: element has definite volume, irregular shape
Gas: element has irregular volume, irregular shape
Plasma: same properties as gas, but electrons of atoms are free-roaming, not orbiting their nuclei.
