Matter in Our Surroundings – Hindi Medium
Matter is anything that has mass and occupies space. In Class 9 Science, the chapter “Matter in Our Surroundings” introduces the fundamental concepts of matter, its states, and properties. Matter exists in three main states – solid, liquid, and gas – each having distinct characteristics like shape, volume, and compressibility. This chapter also explains the particle nature of matter and how particles are in constant motion.
Students learn about the effect of temperature and pressure on matter, leading to interconversion of states such as melting, evaporation, condensation, and sublimation. Important topics include latent heat, boiling point, and evaporation in daily life examples.
This chapter lays the foundation for higher studies in chemistry and physics by explaining how matter behaves under different conditions. NCERT Class 9 Science provides simple explanations, diagrams, and activities to make the concept easy and practical.
