Question

4. Explain the following on the basis of the kinetic theory.
(a) Boiling (b) Melting (c) Condensation​

Answer 1

Answer:

If more heat energy is supplied,the particles eventually move fast enough to break all the attractions between them and the liquid boils.The heat energy required to convert 1 mole of liquid into gas at its boiling point is called the enthalpy and vaporisation

Melting:

Only increasing the temperature of solid the kinetic energy the particles start vibrating with greater speed .The temperature at which a solid melts to become a liquid at the atmosphere pressure it's called it's Melting point

condensation :

On heat liquids ,the temperature rises.particles gain energy.The in molecules.the intermolecule force of attractions decrease intermolecule space between a molecule of liquid at the atmosphere pressure become convert into gas

Answer 2

Answer:

melting is only
