Heat and Thermodynamics question

2021 · 18 Mar · Shift 2 · Q59

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
An ideal gas in a cylinder is separated by a piston in such a way that the entropy of one part is S1 and that of the other part is S2. Given that S1 > S2. If the piston is removed then the total entropy of the system will be :
  1. A
    S1 −-− S2
  2. B
    S1S2{{{S_1}} \over {{S_2}}}S2​S1​​
  3. C
    S1 ×\times× S2
  4. D
    S1 + S2
