... through equation of state. Simply stated equation of state represents a relationship between state variables. For example, if our system is made up of ideal gas then we may use PV= nRT as way to eliminate one of the 4 state variables. So to specify the state of an ideal gas we only need 3 state vari ...

... All thermodynamic systems generate waste heat. This waste results in an increase in entropy, which for a closed system is a quantitative measure of the amount of thermal energy not available to do work. Entropy in any closed system always increases; it never decreases. Additionally, moving parts pro ...

... This work is, however, reversible, since it is the precisely equal to the work which has to be done to bring the gas back to its initial state, releasing the heat Q to the external reservoir. It is rather easy to convince yourself that Wirr < Wrev. Thus if we let the external pressure Pext be less t ...
