Chemistry is the branch of science that deals with the study of matter, its properties, composition, structure, and the changes it undergoes during chemical reactions. It is significant in daily life because it helps us understand the materials around us, from the food we eat to the products we use. Chemistry plays a role in cooking, cleaning, health (medicine), environmental protection, and energy production. For example, the chemical reactions that occur in our bodies enable metabolism, while cleaning products are formulated based on chemical interactions to remove dirt and bacteria.
