  Classification of Matter & States of Matter | Simple NEET Chemistry Notes 1.2 Nature of Matter (NEET Notes  Classification of Matter and States of Matter explained with simple diagrams for easy NEET revision. - Dr.Sanjaykumar Pawar  What is Matter? Matter is anything that has mass and occupies space . Every object around us is matter. Examples: book, pen, pencil, water, air, plants, animals. All living and non-living things are made up of matter. Key idea: If it has weight (mass) and takes up space (volume) → it is matter. 1.2.1 States of Matter Basic idea Matter exists in three physical states : Solid Liquid Gas Particle nature of matter (VERY IMPORTANT for NEET) 1. Solid state Particles are very closely packed . Arranged in a fixed, orderly pattern . Particles have very little movement (only vibration). Strong force of attraction between particles. Resulting properties: Definite shape Definite volume Not compressible easily Ex...
