Which gas law relates to the volume and pressure of a gas?

Boyle's Law specifically relates to the volume and pressure of a gas, expressing the inverse relationship between the two. According to Boyle's Law, when the temperature of a gas is held constant, the volume of the gas varies inversely with its pressure. This means that if the pressure increases, the volume decreases, and vice versa, as long as the temperature remains unchanged. This principle is fundamental in understanding how gases behave under varying pressures, making it essential knowledge for anyone studying aviation and the properties of gases in flight.

The other laws mentioned do not address the relationship between volume and pressure directly. Charles's Law pertains to the relationship between volume and temperature, Dalton's Law deals with partial pressures of gases in a mixture, and Henry's Law focuses on the solubility of gases in liquids under pressure. Understanding Boyle's Law is crucial for recognizing how changes in altitude and cabin pressure can affect the volume of gases in both the human body and aircraft systems.
