Which equation would a technician use when calculating Boyle's law?

Boyle's law describes the relationship between the pressure and volume of a gas at constant temperature. According to Boyle's law, the product of the pressure and volume before a change (P1V1) is equal to the product of the pressure and volume after the change (P2V2), as long as the temperature remains constant. This foundational principle in thermodynamics highlights that when the volume of a gas increases, its pressure decreases, and vice versa, provided the temperature does not vary.

The equation P1V1 = P2V2 is the correct representation of Boyle's law, demonstrating this inverse relationship. Understanding and applying this equation is crucial in fields such as fluid dynamics and engineering, where gas behavior under varying pressures and volumes is a common concern.
