What will happen to the pressure of gas as it is compressed in a smaller volume, assuming constant temperature?

When gas is compressed into a smaller volume while maintaining a constant temperature, the pressure of the gas will increase. This phenomenon is described by Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume when temperature is held constant. Therefore, if the volume decreases, the space available for the gas molecules diminishes, which results in more frequent collisions against the walls of the container. This increase in the frequency of collisions directly leads to an increase in pressure.

Consequently, the relationship dictated by Boyle's Law demonstrates that a reduction in volume leads to an increase in pressure, given that temperature remains unchanged. This fundamental concept is crucial for understanding gas behavior in various applications, including those encountered in millwright practices, where controlling pressure and volume can impact system efficiency and safety.
