Matter- Its Nature and Behaviour
This Unit of NCERT Class 9 science deals with the theme of Materials which includes
Unit I: Matter-Nature and Behaviour
Definition of matter; solid, liquid, and gas; characteristics – shape, volume, density; change of statemelting (absorption of heat), freezing, evaporation (cooling by evaporation), condensation, sublimation.
Nature of matter: Elements, compounds, and mixtures. Heterogeneous and homogenous mixtures, colloids, and suspensions. Physical and chemical changes (excluding separating the components of a mixture).
Particle nature and their basic units: Atoms and molecules, Law of Chemical Combination, Chemical formula of common compounds, Atomic and molecular masses.
Structure of atoms: Electrons, protons and neutrons, Valency, Atomic Number and Mass Number, Isotopes and Isobars.
To strengthen the NCERT Class 9 Science Chapter problem conceptual understanding is not only necessary for the exams but they are also crucial for building fundamentals for upcoming boards class.Â
