Isotherms o an ideal gas. The curved lines represent the relationship atween pressur (on the vertical, y-axis) an volume (on the horizontal, x-axis) for an ideal gas at different temperaturs: lines that are farther away frae the origin (that is, lines that are nearer tae the tap richt-haund corner o the diagram) represent heicher temperaturs.

The ideal gas law is the equation o state o a hypothetical ideal gas. It is a guid approximation o the behaviour o mony gases unner mony condeetions, awtho it haes several leemitations. It wis first statit bi Émile Clapeyron in 1834 as a combination o the empirical Boyle's law, Charles' law an Avogadro's Law.[1] The ideal gas law is often written as
