All change in their form in relation to amount of heat energy.
Explanation:
Due to the chemicals bonds that are within these forms of matter. The solids are compact and have strong bonds where the atomic molecules are attached to each other firmly.
While in gases the bonds are least developed and molecules are able to move freely with the least friction. In water, the bonding is neither compact nor loose.
All this is possible due to the addition of heat to molecules as they gain energy they start to move. Hence changes their forms, while the water molecules one hydrogen bond that is attached to nonbonding pairs of electrons. The water molecules form and reform continuously.
