After emptying her lungs, a person inhales 4.2 L of air at 0.0oC and holds her breath. How much does the volume of the air increase as it warms to her body temperature of 37oC?

0.57 liters

Explanation:

0 C = 273 K

37 C = 37 + 273 = 310 K

Assume ideal gas under constant atmospheric pressure. We know that volume and temperature are proportional to each other

Sp the air volume must have increased by 4.77 - 4.2 = 0.57 Liters

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
