What is the ideal gas law equation?

The ideal gas law equation is expressed as PV = nRT, where P represents the pressure of the gas, V is its volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the absolute temperature in Kelvin. This equation combines several fundamental gas laws, providing a comprehensive relationship between these variables.

The ideal gas law is particularly valuable because it applies to an ideal gas, allowing for predictions about the behavior of gas under varying conditions. For example, one can easily calculate how changes in temperature or volume will affect pressure, and vice versa. This law assumes that gases behave ideally, meaning they occupy no volume and experience no intermolecular forces, allowing for simplification in calculations. It is widely used in chemistry and physics to understand and predict the behavior of real gases under many conditions, making it a foundational concept in these fields.
