In other lessons, we learned about different gas laws: Boyle’s Law, Charles’ Law and Gay-Lussac’s Law. What happens if we combine all these laws together? We come up with a whole new gas law: The Combined Gas Law. This will be our lesson’s focus.

!!!Combined Gas Law: A Combination of Three Laws

There are three variables that we are looking at when it comes to the combined gas law, and these are pressure, temperature and volume. The __combined gas law__ makes use of the relationships of pressure, volume and temperature with each other, which were discussed in other gas laws, namely, Boyle’s Law, Charles’ Law and Gay-Lussac’s Law. To fully understand the combined gas law, let’s take a quick moment to review the basic principles of these laws.

Divers swim several feet under water. Let’s try to think how their lungs are affected. Swimming several feet underneath the water’s surface makes it very hard to breathe. Imagine you are the diver, and you start off with lungs full of air. As you go deeper in the water, the pressure you experience in your lungs increases. When this happens, the air inside your lungs gets squished, so the volume decreases. This demonstrates __Boyle’s law__, which states that the higher the pressure (P), the lower the volume (V), as shown below. Here, k is any constant number. __Boyle’s Law: Relationship between pressure and volume__
