This chapter lays the groundwork for understanding the physical world. Key topics include the Kinetic Theory of Matter, the characteristics of particles (atoms, molecules, ions), the states of matter (solids, liquids, gases), and the processes of interconversion like melting, evaporation, condensation, and sublimation. Solutions will clarify the difference between mass and weight and explain concepts like inter-particle space and attraction.
Types of chemical reactions: Combination, Decomposition, Displacement, and Double Displacement.
