A solid body of constant heat capacity $1\ J/^o C$ is being heated by keeping it in contact with reservoirs in two ways :

$(i)$ Sequentially keeping in contact with $2$ reservoirs such that each reservoir supplies same amount of heat.

$(ii)$ Sequentially keeping in contact with $8$ reservoirs such that each reservoir supplies same amount of heat.

In both the cases body is brought from initial temperature $100^o C$ to final temperature $200^o C$. Entropy change of the body in the two cases respectively is :

  • A$ln $ $2$,$ln $ $2$
  • B$ln$ $2$,$2ln$ $2$
  • C$2$ $ln$ $2$,$8ln$ $2$
  • D$ln$ $2$,$4ln$ $2$

    Two Carnot engines $A$ and $B$ are operated in succession. The first one, $A$ receives heat from a source at ${T_1} = 800K$ and rejects to sink at ${T_2}K.$. The second engine $B$ receives heat rejected by the first engine and rejects to another sink at ${T_3} = 300K.$ If the work outputs of two engines are equal, then the value of ${T_2}$ is .... $K$
