Conventional Standard States
Many standard states are non-physical states, often referred to as "hypothetical states". Nevertheless, their thermodynamic properties are well-defined, usually by an extrapolation from some limiting condition, such as zero pressure or zero concentration, to a specified condition (usually unit concentration or pressure) using an ideal extrapolating function, such as ideal solution or ideal gas behavior, or by empirical measurements.

“Westminster Abbey is nature crystallized into a conventional form by man, with his sorrows, his joys, his failures, and his seeking for the Great Spirit. It is a frozen requiem, with a nations prayer ever in dumb music ascending.”
