If someone takes a breath and the lungs expand from 4.0 L to 5.9 L in volume, and the initial pressure was 752 mm Hg, what is the pressure (in mm Hg) inside the lungs before any additional air is pulled in?
thank you

If someone takes a breath and the lungs expand from 3.3 L to 5.9 L in volume, and the initial pressure was 758 mm Hg, what is the pressure (in mm Hg) inside the lungs before any additional air is pulled in?
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)
Problem 17.5 After emptying her lungs, a person inhales 4.0 L of air at 2.0 ∘C and holds her breath. Part A How much does the volume of the air increase as it warms to her body temperature of 36 ∘C ? Express your answer using two significant figures.
4.0 101 56 How many moles of gases are contained in a human breath that takes in 0.50 L of air at 1.0 atm pressure and 37 °C? PV A 0.165 mol B 2.0 moł D 2.1 mol 1.2 mol NT
An ideal gas is allowed to expand from 7.20 L to 10.8 L at constant temperature. By what factor does the volume increase? factor: The pressure will decrease by that same factor. increase by that same factor. If the initial pressure was 113 atm, what is the final pressure? Pinal = The volume of a sample of hydrogen gas was decreased from 14.32 L to 7.61 L at constant temperature. If the final pressure exerted by the hydrogen gas sample...
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.
How many joules of net work does this person's lung do during one complete breath? Express your answer to three significant figures and include the appropriate units Constants Work Done by the Lungs. The graph (Figure 1) shows a pv diagram of the air in a human lung when a person is Inhaling and then esthaling a deep breath Such graphs, obtained in clnical practice, are normally somewhat curved, but we have modeled one as a set of straight lines...
A volume of 2.8 L of air at 36°C is expelled from the lungs into cold surroundings at 0.3°C. What volume does the expelled air occupy at this temperature? The pressure and the number of gas particles do not change. Answer in L
An ideal gas is allowed to expand from 3.80 L to 17.1 L at constant temperature. By what factor does the volume increase? factor: The pressure will increase by that same factor. decrease by that same factor. If the initial pressure was 131 atm, what is the final pressure? Pinal =
