MCQ

A thermodynamic system is taken from an original state $D$ to an intermediate state $E$ by the linear process shown in the figure. Its volume is then reduced to the original volume from $E$ to $F$ by an isobaric process. The total work done by the gas from $D$ to $E$ to $F$ will be $......J$

A
$-450$
✓
$450$
C
$900$
D
$1350$

✓

Answer

Correct option: B.

$450$

b
$W _{ DE }=\frac{1}{2}(600+300) 3\,J$

$=1350\,J$

$W _{ EF }=-300 \times 3=-900\,J$

$W _{ DEF }=450\,J$
