The figure shows a process $AB$ undergone by $2$ moles of an ideal diatomic gas. The process $AB$ is in such a way that $VT =$ constant. $T_1 = 300 K $and $T_2 = 500 K$ ( $R = $ gas constant)
  • AThe molar heat capacity of gas in the process $A \rightarrow B$ is $5\frac{R}{2} J/mol-K$
  • BThe molar heat capacity of gas in the process $A \rightarrow B$ is $R J/mol-K$
  • CThe work done by the gas is $-400R J$
  • DThe work done by the gas is $-200R J$

    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 .... $K$
