According to Boyle's Law, what happens to gas volume when altitude increases?

• A. Gas volume decreases
• B. Gas volume remains constant
• C. Gas expands
• D. Gas compresses

Answer: (C)

Boyle's Law states that for a fixed amount of gas at a constant temperature, the volume of the gas is inversely proportional to the pressure it is under. As altitude increases, atmospheric pressure decreases. This reduction in external pressure allows gas to expand. Therefore, when altitude increases, the volume of a gas will expand if it is free to do so, in accordance with Boyle's Law. In the context of high-altitude environments, gases in a sealed container or in an inflated object (like a balloon) will exhibit an increase in volume as the atmospheric pressure decreases. Understanding this principle is vital for anticipating changes in gas behavior during air travel or in any high-altitude scenarios relevant to critical care air transport.
