Transcript of Gas Laws in Breathing

Take a deep breath. We all need the air in our lungs to survive. How does this work? What just happened when you sucked in a lot of air and then released it? Gas Laws in Breathing Charles' Law- So how do these apply to you and I breathing? Boyle's Law Applies! Charles' Law Applies! I hope you enjoyed learning how gas laws apply to you breathing! You have seen Charles' law and Boyle's law. And you know what is involved int he breathing process. So carry on and... Don't forget to take a moment to breath deeply! Gas Laws Temp Volume V1/T1=V2/T2 Boyle's Law- Pressure Volume P1V1=P2V2 Outside air pressure*outside volume=
The air pressure in your lungs*the volume of air in your lungs Outside air pressure= 29 units
Outside volume= 48 units
If you breath in 12 units of this air what is the pressure in your lungs?
Divide both sides by 12
The Pressure in your lungs is 116 units. This can work the other way when you breath out just reverse everything! The volume of air in your lungs/the temperature of that air=
the new volume of air in your lungs(after you breath in)/ the new temperature of air. You have 5 units of air in your lungs. You inhale 3 units of air. The temperature in your lungs is 37 degrees C. How warm is the air in your lungs after you breath it in?
