Before you begin to really study gases, you must know what gases are (as opposed to the other common phases of matter) and it may help to understand a bit about phase changes as well.
In addition, it is vital that you understand vacuums (not vacuum cleaners, that comes later) and that you understand a few things about the word suction.
As you begin to study gases, you will need to understand the four properties of gases that can be measured (V, T, n, and P) and the units with which we measure them. In trying to understand pressure, you will need to spend some time learning about how we measure pressure, which is based on the “technology” of drinking straws.
Once you know the four properties of gases, you will need to learn about Kinetic Molecular Theory (KMT) and you will learn to relate KMT to the 2-variable laws (laws that relate one property of a gas to another) such as Boyle’s Law, Gay Lussac’s Law, Charles’ Law, the Un-Named Law, and Avogadro’s Law. These laws will lead to solving IF problems (also called combined gas law problems).
You will also need to study several other gas laws such as Dalton’s Law (and associated problems), The Ideal Gas Law (and associated problems) and Graham’s Law (and associated problems).
Lastly, you will need to learn a little bit about non-ideal behavior of gases and will want to look into some real-world applications of gases and gas behavior.
