Which gas law is applied to calculate the contents of an oxygen cylinder?

Boyle's Law is applicable for calculating the contents of an oxygen cylinder because it describes the relationship between the pressure and volume of a gas when the temperature is held constant. According to Boyle's Law, as the volume of gas decreases, the pressure increases, and vice versa, which is critical for understanding how gas behaves in a cylinder during filling, usage, and varying conditions.

In an oxygen cylinder, the gas is often compressed, and monitoring its pressure allows for the determination of how much gas remains in the cylinder. As the gas is used, the volume of gas inside the cylinder changes, impacting the pressure readings which are vital for safe usage and determining how much oxygen is available for the user. This relationship is fundamental when dealing with gas cylinders in medical and industrial settings, ensuring an understanding of how to operate devices safely and efficiently.
