Typically, when a person coughs, he or she first inhales about 2.10 L of air at 1.00 atm 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 atmospheres.

An adult inhales approximately 12 times per minute, taking in about 500 mL of air with each inhalation. Oxygen and carbon dioxide are exchanged in the lungs, but there is essentially no exchange of nitrogen. The exhaled air has a mole fraction of nitrogen of 0.75 and is saturated with water vapor at body temperature, 37°C. If ambient conditions Professor Christina Tang, [email protected] 2 are 25°C, 1 atm and 50% relative humidity, determine what volume of liquid water (mL) would...

When a person gets an influenza vaccine, he or she is less likely to get sick with the flu. This makes it less likely for that person to pass the flu to someone else. Suppose that the external benefit created by the influenza vaccination is equal to $100 per dose. (a) In a diagram, show the equilibrium in the influenza vaccine market. Also, show the quantity that would maximise social surplus. Is this equal to the perfectly competitive market equilibrium...

In many foreign countries a person cannot become a judge unless he or she first attended a formal college for judges, has passed a rigid set of exams or has had many years of specialized training. The United States, however, imposes no formal requirements whatsoever on a prospective federal judge; the presidential appointee need only be approved by the Senate. Would the U.S. benefit from emulating the model of other nations or has the U.S. system served the citizenry well?
