An ideal gas in a cylinder is separated by a piston in such a way that the entropy of one part is S1{S}_{1} and that of the other part is S2{S}_{2}. Given that S1>S2{S}_{1} > {S}_{2}. If the piston is removed then the total entropy of the system will be: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 theAn 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

Options

  1. AS1×S2{S}_{1} \times {S}_{2}
  2. BS1−S2{S}_{1} - {S}_{2}
  3. CS1S2\dfrac{{S}_{1}}{{S}_{2}}
  4. DS1+S2{S}_{1} + {S}_{2}

Correct answer

D. S1+S2{S}_{1} + {S}_{2}

Step-by-step solution

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
;S1>S2; {S}_{1} > {S}_{2}

After piston is removed

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|
;Stotal=S1>S2; {S}_{total} = {S}_{1} > {S}_{2}
