The kinetic theory considers all matter( substances) to be made up of particles which are in continuous motion. 

Theoretically, heating a solid to higher and higher temperatures changes its phase to a liquid, and finally to a gas.
A solid consists of low kinetic energy vibrating particles locked into position by interparticle attractive forces. When heat is applied, energy is absorbed and the particles start vibrating more vigorously.

Molecules in solid are tightly packed together and cannot move.

In liquid and solid states the bond lengths and bond angles are slightly changed due tohydrogen bonding.

Water vapour at 373K has more energy than water at 373K as the steam has absorbed latent heat of vaporisation to change the state. Therefore the more burning sensation.

Quicklime when added to water, it reacts with water chemically and form a suspension of slaked lime in water and produce heat energy. So it also results in an increase in temperature of the mixture.

Solids do not mix with each other as there is very less space between the atoms of solids and are tightly packed.

Solid has highest inter-molecular force of attraction. Liquids has inter-molecular force of attraction less than solid but greater than Gas. So, it has indefinite shape but definite volume.
