How long does it take a person at rest to breathe one mole of air if the person breathes 85.0 mL s of air that is measured at 25 °C and 755 Torr?
Express your answer numerically in seconds.
Transcribed Image Text:Part B
Typically, when a person coughs, he or she first inhales about 2.00 L of air at 1.00 bar and 25 °C. The epiglottis and the vocal cords then shut, trapping the air in the lungs, where it is warmed to 37 °C
and compressed to a volume of about 1.70 L by the action of the diaphragm and chest muscles. The sudden opening of the epiglottis and vocal cords releases this air explosively. Just prior to this release,
what is the approximate pressure of the gas inside the lungs?
Express your answer numerically in bars.
