What is Matter?
Matter is anything in the universe that is made out of atoms. Atoms are tiny building blocks of all things. Check out our post on atoms! Matter comes in three states: solids, liquids, and gases. We are going to write about each one of them in the next few days. Today, we are going to focus on the gas state of matter.
What is a Gas?
Gases have atoms that are spread very far apart. This makes gases very light and have no definite size or shape! Gases are found everywhere in the universe! Gases are able to float because they tiny atoms in gases are so light that small updrafts of wind can make them float! When gases are cooled down, they become a liquid. Those are the properties of gases!
