What is a “standard state”?

A standard state is a set of reference conditions with respect to which properties can be described/calculated under other conditions. For example, the properties at standard-state conditions of a gas may be defined by its properties at 293.15 K and 1 bar of pressure. Knowledge of the properties of a gas under these standard conditions can be used to calculate the properties under other conditions.
