Module 3 Intro

Module 3—Behaviour of Gases

Lesson Summary

 

In this lesson you investigated the following questions:

• What is pressure?
• How is pressure measured?
• How are pressure and volume of a gas related?
• How are pressure-volume relationships applied in technologies to support breathing?

Gases are essential to life on Earth. In this lesson you learned about the mechanics of breathing and how this is an example of a pressure-volume relationship of a gas. You also learned how technologies to assist breathing must incorporate an understanding of pressure-volume relationships in order to function appropriately.

 

As you will see in the next lessons, an understanding of Boyle’s law is only one part of understanding the behaviour of gases.
