Matter And Its Properties covers the basic concepts about the matter. Matter And Its Properties are simplified and precise that are easy to understand.
Matter And Its Properties
Matter – Anything that has volume and mass.
Classification of Matter:
(1) Physical Classification
(2) Chemical Classification
| Physical Matter |
|---|
| (1) Solids >Definite Shape and Size >Particles are Tightly packed >High density >Almost incompressible >High Boiling Point (BP); Melting Points (MP) |
| (2) Liquids >Definite Volume but no fixed shape >Not so tightly packed >Lower density than Solids >Compressible >Lower BP and MP than Solids |
| (3) Gasses >No definite shape and size >Loosely packed >lower density than Liquids and Solids >Highly compressible >Lower BP and MP than Liquids and Solids |
| (4) Plasma >fourth state of matter >Described by Irving Langmuir >Occurs at very high temperature >Found in Stars including the Sun >Equal no of +ve and –ve charged particles >Ionized state of matter |
| (5) Bose-Einstein Condensate >Fifth state of matter >Predicted by SN Bose and Einstein >Achieved at absolute zero (0 K) temperature >Atoms and Atomic sub-particles are at rest >Zero Entropy (No disordered state) |
Change of State of Matter
Melting: Conversion of a solid into a liquid
Freezing: Conversion of a liquid into solid
Vaporization: Conversion of a liquid into gas
Condensation: Conversion of gas into liquid
Sublimation: Conversion of a solid directly into a gas
Deposition: Conversion of gas directly into a solid
Ionization: Conversion of matter into ionized particles
Recombination: Deionisation of particles
| Chemical Matter |
|---|
| (1) Pure Substances (a) Elements (Metals, Non-metals, and Metalloids) (b) Compounds (Organic and Inorganic compounds) |
| (2) Mixtures (a) Homogeneous Mixture (Solutions) (b) Heterogeneous Mixture (Colloids and Suspensions) |
