Cambridge IGCSE Chemistry has been developed by Kversity subject experts. Chemistry is the branch of science dealing with the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. Many people think of chemists as being white-coated scientists mixing strange liquids in a laboratory, but the truth is we are all chemists. Understanding basic chemistry concepts is important for almost every profession. Chemistry is part of everything in our lives.
Every material in existence is made up of matter-even our own bodies. Chemistry is involved in everything we do, from growing and cooking food to cleaning our homes and bodies to launching a space shuttle. Chemistry is one of the physical sciences that help us to describe and explain our world. The chemistry has three broad branches, Organic Chemistry, Inorganic Chemistry and Physical Chemistry.
