Elaborate the statement that physical state of existence at given conditions is a balance between the thermal energy and intermolecular forces.
Intermolecular forces tend to keep the molecules together but thermal energy of the molecules tends to keep them apart. The three states of matter are the result of the balance...

Explain the effect of increasing the temperature of a liquid, on intermolecular forces operating between its particles.
On increasing the temperature, the kinetic energy of liquid molecules increases so that it can overcome the attractive forces between the molecules and hence liquid can flow more easily i.e....
