Difference in physical property between H2O and D2O to be explained.

Concept introduction

Every atom strives to attain lowest possible energy in their shells. This is the driving force of atoms to combine with other atoms in so called “chemical reactions”. At the lowest possible energy levels, atoms and molecules attain utmost stability.

Reaching the lowest energy is not only the essential criterion for the molecules of matter to be stable. There are many other factors that have role in determining the stability of a substance. “Intermolecular forces” and “Intramolecular forces” are two such factors that have significant impact on the stability of matter.

In simple words, Intermolecular forces are termed as the forces acting “between molecules” that is components of a substance. Intramolecular forces are the forces that operate “within a molecule”. The prefix “inter” mean “among” and “intra” mean “within”.

Atoms do combine to form a molecule. Within a molecule, the atoms are held together by intramolecular forces. Many molecules are formed by such instance. Matter is composed of many such innumerable molecules which are held together by intermolecular forces.
