An ideal gas in a cylinder is separated by a piston in such a way that the entropy of one part is $\displaystyle \mathrm{S}_1$ and that of the other part is $\displaystyle \mathrm{S}_2$. Given that $\displaystyle \mathrm{S}_1>\mathrm{S}_2$. If the piston is removed then the total entropy of the system will be :
Official answer
(3)
$\displaystyle \mathrm{S}_1+\mathrm{S}_2$
