Final answer:
The new volume of the gas in the lungs is approximately 2.35 liters.
Step-by-step explanation:
To find the new volume of the gas, we can use the combined gas law equation:
V1/T1 = V2/T2
Where V1 is the initial volume,
T1 is the initial temperature,
V2 is the new volume, and
T2 is the new temperature.
Plugging in the given values:
V1 = 2.2 liters
T1 = 18°C = 18 + 273 = 291K
T2 = 38°C = 38 + 273 = 311K
Solving for V2:
V2 = (V1 * T2) / T1
V2 = (2.2 * 311) / 291
V2 ≈ 2.35 liters
So, the new volume of the gas in the lungs is approximately 2.35 liters.
