Second Law of Thermodynamics

The second law of thermodynamics (entropy) states that heat cannot pass from a cold body to a hot one by a self-acting process without the help of an external influence.  Entropy is the measure of disorder within a system. The more disorder within the system, energy becomes less available to do work.

 

Second Law of Thermodynamics formula

\(\large{ \Delta S = \frac {\Delta Q} {T}   }\)

Where:

\(\large{ \Delta S }\) = entropy differential

\(\large{ \Delta Q }\) = heat differential (energy)

\(\large{ T }\) = temperature
