Ideal Gas Law

The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations. It was first stated by Émile Clapeyron in 1834 as a combination of the empirical Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law. The ideal gas law is often written as
    • Equation 

    • Energy associated with a gas 

    • Applications to thermodynamic processes 

    • Deviations from ideal behavior of real gases 

    • Derivations
