AI Thread Summary
The volume of air in the lungs increases as it warms from 0.0 °C to body temperature at 37 °C due to thermal expansion. When a person inhales 4.1 L of air and holds their breath, the volume remains constant initially, but the air expands as it heats. The discussion suggests using Charles' Law or the general gas law to calculate the change in volume. It is important to assume that pressure remains constant during this process. Ultimately, the inhaled air will occupy a greater volume when exhaled at body temperature.

Homework Statement



After emptying her lung, a person inhales 4.1 L of air at 0.0 oC and holds her breath.
How much does the volume of the air increase as it warms up to her body temperature at 37 o?

Homework Equations


No equation through my notes I could find



The Attempt at a Solution


I figured in since the person is holding breath the volume doesn't change unless they were to release therefore keeping the volume at 4.1L

I think you probably are intended to consider the pressure remaining constant at prevailing atmospheric pressure. The inhaled air expands as it warms, so that when you are about to exhale, you have more volume to empty.

You can use Charles' Law or the general gas law.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
