Chemistry

Chemistry is a branch of physical science that studies matter and how matter changes. Chemistry is often called the “central science” because it is so important in the understanding of many of the other branches of science.

Chemistry is often believed to be the most difficult of the sciences to study, however, upon further examination we can see that this is not the case. We often use concepts and skills related to chemistry in daily life without even knowing it. For example, if you have ever used a recipe to bake or cook you have used a skill that is often used in chemistry. If you have ever determined how many millitres there are in a litre or how many ounces there are in a pound then you have used a skill that is often used in chemistry.

Chemistry is a very broad area of science and is can be separated into five subcategories.

  1. Physical Chemistry
  2. Organic Chemistry
  3. Inorganic Chemistry
  4. Analytically Chemistry
  5. Biochemistry

 

The universe contains all matter and energy.

The universe contains all matter and energy.

So, chemistry is the study of matter but what is matter?

 

Matter is anything that has mass or takes up space (has a volume). In other words, matter is basically every physical thing in the universe. There are really only two “things” in the universe; matter and energy. Throughout the proceeding lessons we will explore how these two “things” relate to each other. First, we will learn in the next lesson about the properties of matter.
