Module 4 Project:
Gas Laws and Breathing
The purpose of respiration is the exchange of gases.
It requires an inhalation (breathing in) and
exhalation (breathing out).
The activity of respiration is dictated by the different gas laws.
Module 4 Project, you will explore gas laws in respiration.
The purpose of this project is to understand how gas laws affect our daily lives. This will help us
to use gas laws on a daily basis and create an understanding as to why they are important to us.
This project also allows us to think about differences between gas laws and what gas law to
implement in a problem.
Chapter 8 - Role of Gas Laws and Breathing
During Respiration, there is a gas exchange due to changes in Boyle’s Law.
YouTube on Boyle's Law and Respiration
(Time 1:56 minutes) and see website

showing Boyle's Law and Respiration
to answer the following
Write out the equation for Boyle’s Law and Explain
what is Boyle’s
Law (write this out in your own words as though you might be trying
to explain it to a friend).
Using the image below, Explain
how the variables of Boyle’s Law
(pressure, volume and temperature) change during the process
during Inhalation and during Exhalation
What roll does the
Diaphragm have in this process?
