Question

an average adult inhales a volume of 0.50 liter of air into the lungs with each breath.If the air is warmed from room temperature (20 degree celsius) to body temperature (37 degree celsius),what is the volume of air exhaled?

Answer 1

assuming the pressure is the same, and, assuming no O2 is dissolved in the blood, and assuming no CO2 leaves the body....

V1/T1= V2/T2

V2=V1T2/T1=.5*(273+37)/(273+20)
