How is Boyle's Law expressed mathematically?

Boyle's Law, which describes the inverse relationship between the pressure and volume of a gas at constant temperature, is mathematically expressed as the product of pressure and volume being constant. This is represented by the equation P1 x V1 = P2 x V2. In this equation, P1 and V1 represent the initial pressure and volume, while P2 and V2 represent the final pressure and volume after a change occurs.

According to this law, when the volume of a gas decreases, the pressure increases, provided the temperature remains constant. This relationship showcases the fundamental principle of gas behavior, which is critical in understanding various refrigeration and HVAC processes.

The focus on the product of pressure and volume being equal before and after a change is essential because it allows technicians and engineers to predict how changes in one variable affect the other. This practical application is crucial in managing systems efficiently in refrigeration practices.
