Which law states that the pressure of a gas increases as the volume decreases, while temperature remains constant?

Boyle's Law describes the relationship between the pressure and volume of a gas when the temperature remains constant. According to this law, if the volume of a gas decreases, the pressure exerted by the gas will increase, assuming the temperature does not change. This behavior occurs because the gas molecules have less space to move around, leading to more frequent collisions with the walls of the container, which raises the pressure.

The other laws mentioned relate to different aspects of gas behavior. Charles's Law focuses on the relationship between volume and temperature of a gas, Avogadro's Law deals with the volume of gas at constant temperature and pressure being directly proportional to the number of gas molecules, and Bernoulli's Principle addresses the behavior of fluid dynamics and the relationship between pressure and velocity in fluids. Understanding Boyle's Law is crucial for applications involving gas behavior under varying pressure and volume conditions.
