What does Boyle's Law state about gas behavior?

Boyle's Law is a fundamental principle in thermodynamics that specifically addresses the relationship between the pressure and volume of a gas at a constant temperature. According to Boyle's Law, for a fixed mass of gas, as the pressure on the gas increases, the volume decreases, indicating that pressure and volume are inversely related. This mathematically can be expressed as P1V1 = P2V2, where P is the pressure and V is the volume of the gas at two different states.

This law highlights the behavior of gases under constant temperature conditions, often referred to as isothermal conditions. The underlying reason for this inverse relationship is that increasing pressure on a gas forces the molecules closer together, reducing the space they occupy, and thereby decreasing the volume. Conversely, if the volume of the gas increases, the pressure exerted by the gas must decrease, assuming the temperature remains constant.

Understanding Boyle's Law is crucial in applications involving gases, such as in various scientific and engineering fields where gas behavior under pressure and volume changes is relevant.
