winter 2015 final Q3 C

Postby Jose_Arambulo_2I » Thu Mar 16, 2017 10:38 pm

To calculate the volume after inhalation, why are you supposed to add the initial volume, 2.500L, by 0.705L. I don't understand how 0.705L is the delta V. If anything, shouldn't the delta v be 0.705L-0.667L? Because that'd give us the change in volume that accompanies the change in temperature.

The question is asking what is the total air volume in the lungs after inhalation at 37 degrees celsius. In part B, we were told to calculate the volume of air the air at 37 degrees celsius, which we found to be 0.705 L. They gave us the volume of air already in the lungs, 2.500 L, so to find the total volume of air in the lungs at 37 degrees, you simply add 2.500L + 0.705 = 3.205L total.
