Chemistry is the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances. Objects that take up space and have mass are called matter. Everything around you is made up of matter. Even the food you eat is made up of matter. You are made of matter. In this tutorial, you will be introduced to the nature of matter.
The tutorial consists of lessons that explain the nature of matter and covers topics such as what matter is, how matter can be classified, solids, liquids, gases, properties of atoms and the Periodic Table. Even though, a basic knowledge of chemistry will make this tutorial a little bit more interesting, you do not need to have any prior knowledge to take this tutorial. You should find that the lessons are relatively easy to follow.
