An ideal gas heat engine operates in a Carnot cycle between $227\,^oC$ and $127\,^oC$. It absorbs $6\, kcal$ at the higher temperature. The amount of heat (in $kcal$) converted into work is equal to

A

$4.8$

B

$3.5$

C

$1.6$

D

$1.2$

Solution

Use $\eta = 1 – \frac{{{T_2}}}{{{T_1}}} = \frac{W}{Q}$
