Which equation relates pressure, volume, and temperature for an ideal gas?

The equation that relates pressure, volume, and temperature for an ideal gas is known as the Ideal Gas Law. This law is formulated as ( PV = nRT ), where ( P ) represents the pressure of the gas, ( V ) is the volume, ( n ) is the number of moles of the gas, ( R ) is the universal gas constant, and ( T ) is the temperature measured in Kelvin.

The Ideal Gas Law provides a comprehensive relationship that takes into account all three of the state variables (pressure, volume, and temperature) simultaneously, making it easier to predict how a gas will behave under various conditions. For example, if you know the initial state of a gas and change its temperature or volume, you can calculate the resulting changes in pressure using this law.

The other options, while related to gas behavior, do not encompass the relationship between all three variables as a single equation. Boyle's Law focuses specifically on the relationship between pressure and volume at constant temperature, Charles's Law discusses the relationship between volume and temperature at constant pressure, and Avogadro's Principle deals with the volume of gas concerning the number of moles at constant temperature and pressure. Thus, the Ideal Gas Law stands out as
