The process of inhalation in the lung may be modelled (very simplistically) by the pV diagram shown below , in which the pressure drops sharply in the lungs at constant volume, followed by expansion at constant pressure, and then finished by the pressure returning to atmospheric at constant volume. Assume the temperature inside the lungs is steady 37 degrees celsius.
a)How many moles of air are added to the lungs during the inhalation process? how many grams is that?
b) how much work is dones during the entire inhalation process i-f?
