At room temperature (25oC) and normal atmospheric pressure (760 torr), the average person’s lungs have a total capacity of about 5.5 liters. If a person takes a deep breath and then dives deep into a lake where the temperature is 19oC and a pressure of 915 torr, what will be the new volume of air in his lungs?

Answer 1

(P1V1/T1) = (P2V2/T2)
Remember T must be in kelvin.
