On a chilly 12∘C day, you quickly take a deep breath--all your lungs can hold, 4.0 L. The air warms to your body temperature of 37∘C. If the air starts at a pressure of 1.0 atm, and you hold the volume of your lungs constant (a good approximation) and the number of molecules in your lungs stays constant as well (also a good approximation), what is the increase in pressure inside your lungs?

A diver takes a deep breath at the surface where the pressure is 1.0 atm, filling his lungs with 4.0 L of air. He then descends to a depth where the pressure is 0.5 atm higher than at the surface. What is the volume of air in his lungs at this depth given that the air's temperature remains the same? 4 A) 2.67 L B) 8.00 L C) 0.375 L D) 6.00 L E) 0.125 L (181 Finol 014)

On a cold day, you take a breath, inhaling 0.4 L of air whose initial temperature is -10 degree C. In your lungs, its temperature is raised to 37 degree C. Assume that the pressure is 106 kPa and that the air may be treated as an ideal gas. What is the total change in translational kinetic energy of the air you inhaled number? Round your answer to the nearest whole.
