WHAT IS MATTER AND THEIR PHYSICAL STATE
In Chemistry we study Matter in different perception. Matter is anything which occupies space and have mass. Matter may exist in Solid, Liquid, and Gaseous form, but their basic structural unit are small tiny particle, we call it Molecule.
The important aspect in the study of Matter pertains to:
- Physical State of Matter in which they exist.
- Structural Arrangement of Molecule.
- Molecular Composition of Matter.
- Type of Transformation they Undergoes Under Different Condition.
During Physical transformation only Molecular arrangement change as a result Physical Properties also Changed.
KINETIC MOLECULAR THEORY:
The various properties of matter which determine the physical behavior of matter are predicted in Kinetic Molecular Theory.
Postulate of Kinetic Molecular Theory:
- Matter is composed of small tiny particles called Molecule.
- Empty space exist between the Molecules are called Inter Molecular Space.
- Molecules have force of attraction between them called Inter Molecular Force.
- The force of attraction between similar molecule are called Cohesive Force.
- The force of attraction between dissimilar molecule are called Adhesive Force.
Different States of Matter and their Properties
The matter around us can be classified into three different states – Solid, Liquid, Gases
