Question

Any athletes in a kinesiology research study has his lung volume of 7.05dm during a deep inhalation.At this volume the lungs contain 0.312 mole of air
During exhalation the volume of his lung decrease the 2.35dm.How many moles of air does the athletes exhale during exhalation (assume pressure and temperature remain constant)

Answer 1

Answer:

Volume of freon (V1) = 1.5 dm3

Pressure (P1) = 0.3 atm

'T' isconstant

P2= 1.2 atm

V2= ?

∴ P1V1 = P2V2

=0.375 dm3

∴ Volume decreased from 1.5 dm3 to 0.375 dm3
