Physical and Chemical Changes – Class 8 ICSEPhysical and Chemical Changes is an important chapter in ICSE Class 8 Chemistry that introduces students to the different ways in which substances can change. The chapter explains the difference between a physical change, in which the physical properties or state of a substance change without forming a new substance, and a chemical change, in which one or more new substances with different properties are formed.Students learn about the characteristics and examples of physical and chemical changes, including changes in state, dissolving, expansion and contraction, rusting, burning, cooking, and reactions between substances. The chapter also helps students understand whether a change is reversible or irreversible and identify signs that indicate a chemical change.This chapter builds a strong foundation for understanding chemical reactions and changes in matter, making it useful for further study in ICSE Chemistry.Key Topics:Physical changesChemical changesReversible and irreversible changesFormation of new substancesCharacteristics of chemical changesEveryday examples of physical changesEveryday examples of chemical changesDifference between physical and chemical changesEffects of heat and other factors on substances
