Think about the analogy "full of hot air." If a person were to inhale 2.2 L of gas at a temperature of 18 °C and that air heats to a temperature of 38 °C inside the lungs, what would be the new volume of the gas? Round to the nearest hundredth. Don't forget the units.

The Boyle's Law states that
PV/T = k where k is a constant
so, assuming a constant pressure
V/T does not change
2.2/(291.15) = V/(311.15)
V = 2.35 L
