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 doesnt 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.
