Weight changes depending on where you are, but mass stays the same. Understanding chemical reactions, which are important in sustaining life that take place in organisms, helps in understanding life. Many sciences in biology, including microbiology, plants and animal science, are based on chemistry. Because the structure composition and behavior can be … Why Chemistry is Important in Nursing? History of chemistry Chemistry already existed a long time ago. This branch of science involves identifying different substances contained in matter and how they interact and change.

A chemist (from Greek chēm(ía) alchemy; replacing chymist from Medieval Latin alchimista) is a scientist trained in the study of chemistry.Chemists study the composition of matter and its properties. The Egyptians knew how to make glass from sand 4 500 years ago. One who is interested in chemistry may be curious as to what role a chemist plays in today’s society. Organisms are alive because of their chemical composition. Organic chemists can of course contribute directly to OOL research by speculating on and studying the kinds of reactions that would have been important in molecular origins. As early as 8 000 years ago, people in the Middle East extracted metals such as copper and iron for making tools and ornaments. Chemistry is the study of matter and its interactions with other matter and energy. Here's a look at the importance of chemistry and why you should study it. Scientists use significant figures in measured quantities where it is impossible to know an exact number. Why Are Significant Figures Important?
