Therefore, understanding the pressure at which the oxygen is stored is essential for accurate calculation.
The Relationship Between Volume and Pressure
The relationship between volume and pressure can be described by Boyle’s Law, which states that the volume of a gas is inversely proportional to its pressure, assuming the temperature remains constant. Mathematically, this relationship can be expressed as:
V1/P1 = V2/P2
Where:
– V1 is the initial volume of the gas
– P1 is the initial pressure of the gas
– V2 is the final volume of the gas
– P2 is the final pressure of the gas
By rearranging the equation, we can calculate the final volume of the gas:
V2 = (V1 * P1) / P2
This formula allows us to determine the volume of oxygen in a cylinder based on the initial volume and pressure, as well as the desired final pressure.
