Clausius inequality

[′klȯz·ē·əs in·i′kwäl·əd·ē]
(thermodynamics)
The principle that for any system executing a cyclical process, the integral over the cycle of the infinitesimal amount of heat transferred to the system divided by its temperature is equal to or less than zero. Also known as Clausius theorem; inequality of Clausius.

This is a remarkable result with respect to the compound deficiency: the Clausius inequality of closed systems
The Clausius inequality for closed systems can be formulated by use of the contact temperature of the non-equilibrium system or by using the thermostatic temperature of the controlling environment reservoir.
In contrast to the general validity of the Clausius inequality, the corresponding inequality, formulated by use of the contact temperature, marks the difference between an undecomposed system and a composite one:
