Which gas law states that temperature remains constant while pressure and volume have an inverse relationship?

The gas law that describes the relationship between pressure and volume at a constant temperature is Boyle's Law. This principle states that if the temperature of a gas remains constant, increasing the pressure on the gas will decrease its volume, and conversely, decreasing the pressure will increase its volume. This inverse relationship can be mathematically expressed as PV = k, where P is the pressure, V is the volume, and k is a constant.

The significance of Boyle's Law in the context of gases is crucial; it helps explain behavior in various applications, such as in pistons, syringes, and other systems that rely on gas compression and expansion. Understanding this concept is essential for applications in heating, ventilation, and air conditioning technologies, where manipulation of gas volumes and pressures plays a key role in system efficiency and performance.
