Condensation takes place when the atoms or molecules come together and clump due to increased inter-molecular attraction.

At boiling point, the particles of liquid  get converted into a gas.

On cooling gases and liquids, temperature falls intermolecular attraction increases intermolecular space between molecules decreases.

The temperature at which the particles slow down and converts into a liquid is known as liquefaction point.

On the heating matter, the kinetic energy of particles increases, so they gain energy and on the cooling matter, the particle's the motion of particles decreases, so they lose energy.

At melting point, the particles get converted into a liquid.

On cooling a gas, the temperature falls down and the stored potential energy is released in the form of heat energy so that the temperature fall and the gas becomes cool.

The phenomenon of change from one state of matter to another and then back to the original state is called the inter-conversion of states of matter.

Inter-conversion of states of matter is affected by 1. Changing the temperature.
2. Increasing or decreasing the pressure.
3. Changing both temperature and pressure.

Solids have the lowest kinetic energy whereas gases have the highest kinetic energy. Hence, hydrogen has the highest kinetic energy among the above examples.
