Chemistry is the study of matter and the changes it undergoes from "summary" of Chemistry Simplified NCERT Class 11 by Sanjay Sharma
Chemistry is a fascinating subject that revolves around the study of matter and the transformations it goes through. Matter is anything that occupies space and has mass. It can exist in various forms such as solid, liquid, or gas. Chemistry helps us understand the composition, structure, properties, and behavior of matter. The changes that matter undergoes can be physical or chemical in nature. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. For example, melting ice to form water is a physical change since the chemical composition of water remains the same as that of ice. On the other hand, chemical changes result in the formation of new substances with different properties. These changes involve the breaking and forming of chemical bonds. For ins...
