Matter in Our Surroundings Notes CBSE Class 9 Ch 1

Physical Nature of Matter Matter is made up of very small Particles Characteristics of Particles of Matter Particles of matter are continuously moving, i.e., they possess kinetic energy. Kinetic Energy of the particles increases with the increase in temperature. Particles of matter attract each other. States of Matter Due to variation in the characteristics of particles of matter, the matter exists in three states. Solid Liquid Gas Water exists in three states Solid, as Ice Liquid, as Water Gas, as…
