Tips
- write cue cards on respiratory system
- get someone to test you on your notes (friend,Mum,sister,brother ect)
- copy down diagrams of the system
- get someone to test you on Digram
- play online interactive games to test your knowledge on the respiratory system
- go through your textbook write a checklist things you know things you need to improve on.
- watch YouTube clips on the respiratory system
Using ideal gas equation, PV = nRT, and since there is no volume change and amount change, the equation is now P = kT, where k =nR/V. Temperature must be in kelvin
From the given, k = (0.82)/ (21 + 273) = 2.78 x 10^-3
Substituting T = -3.5+273, P = 0.75 atm
