A volume of 2.0 L of air at 37°C is expelled from the lungs into cold surroundings at 1.3°C. What volume (in L) does the expelled air occupy at this temperature? The pressure and the number of gas particles do not change?
The pressure inside a 1.0 L balloon at 25°C was 750 mm Hg. What is the pressure (in mmHg) inside the balloon when it is cooled to −58°C and expands to 3.2 L in volume?

The metabolic breakdown of glucose produces CO2, which is expelled from the lungs as gas.
Place numerical answers to three significant digits in the blanks provided. The metabolic breakdown of glucose produces CO2, which is expelled from the lungs as gas. Calculate the volume of CO2 produced at body temperature when 5.00 g of glucose breaks down. Assume this occurs at 1.08 atm.

A) The total volume of air in Jeffrey’s lungs is 5800 mL. If his
IC is 3200 and his RV is 1000, calculate his ERV and FRC.
B) The total volume of air Sally can inhale after a quiet
exhalation is 3400 mL. When Sally is sitting still she inhales 400
mL and there is 2200 mL left in her lungs. Calculate or figure out
from the information given in the question the following values TV,
TLC, IC, FRC, IRV....

A. A person’s lungs can hold 6.0 L (1 L = 10-3 m3) of air at
body temperature (310 K) and atmospheric pressure (101 kPa). Given
that air is 21% oxygen, find the number of oxygen molecules in the
lungs. [Ans: 3.0 x 10^22]
B. (Continued from the previous question) If the person now
climbs to the top of a mountain, where the air pressure is half
that at the base, does the number of molecules in the lungs change?...
