A head injury can affect the ability of a person to ventilate(breath in and out).
a. What would happen to the partial pressure of oxygen and carbon dioxide in the blood if a person cannot properly ventilate?
b. When a person who cannot breathe properly is placed on a ventilator, an air mixture is delivered at pressures that are alternately above the air pressure in the person's lung, and then below. How will this move oxygen into the lungs, and carbon dioxide out?
A sample of Ar gas has a volume of 5.40 L with an unknown pressure. The gas has a volume of 9.73 L when the pressure is 3.62 atm, with no change in temperature or amount of gas. What was the initial pressure, in atmospheres, of the gas?
A gas sample has a pressure of when the temperature is . What is the final pressure, in atmospheres, when the temperature is , with no change in the volume or amount of gas?
A sample of nitrogen (N2) has a volume of 50.0 L at a pressure of 760 mm Hg. What is the final volume, in liters, of the gas at each of the following pressures, if there is no change in temperature and amount of gas?
a. 725 mmHg
b. 2.0 atm
c. 0.500 atm
d. 850 Torr
