What law relates the pressure, volume, and temperature of an ideal gas?

The Ideal Gas Law is the foundational equation that relates the pressure, volume, and temperature of an ideal gas within a single framework. This law is represented by the equation PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin.

This law encompasses the principles defined by each of the other laws mentioned. Charles's Law specifically focuses on the relationship between volume and temperature while keeping pressure constant, and Boyle's Law examines the relationship between pressure and volume with temperature held constant. Avogadro's Law relates the volume of gas to the number of moles at a constant temperature and pressure.

By integrating these relationships, the Ideal Gas Law provides a comprehensive way to predict the behavior of an ideal gas when any of the variables—pressure, volume, or temperature—change, assuming the amount of gas in moles remains constant. This makes it a crucial tool in chemistry for understanding gas behavior under various conditions.
