Question 12

Chemistry

Answer 12

The study of the composition of matter and the changes that it undergoes.
-chemistry answers many questions you may have about the world
-Chemistry affects mostly all aspects of life because all living and nonliving things are made up of matter
-Chemistry is also known as the central science because it mixes with all other science
FUN FACT: Everything is made up of matter therefore everything contains Chemicals
