State the Kelvin-Planck statement of the second law of thermodynamics.
(N/A) The Kelvin-Planck statement of the second law of thermodynamics states that:
It is impossible for any device that operates on a thermodynamic cycle to receive heat from a single thermal reservoir and produce a net amount of work.
In simpler terms,no heat engine can have a thermal efficiency of $100\%$.
This implies that for a heat engine to operate,it must exchange heat with at least two reservoirs at different temperatures.

An ideal gas in a cylinder is separated by a piston in such a way that the entropy of one part is $S_{1}$ and that of the other part is $S_{2}$. Given that $S_{1} > S_{2}$. If the piston is removed,then the total entropy of the system will be:
