Question 986: Thermodynamics & KTG

Question

An ideal gas heat engine operates in a Carnot cycle between 227
o
C and 127
o
C. It absorbs 6 kcal at the height temperature. The amount of heat (in kcal) converted into work is equal to

Accepted Answer

Efficiency of Carnot engine
$$ = {W \over {{Q_1}}} = 1 - {{{T_2}} \over {{T_1}}}$$
$${W \over 6} = 1 - {{400} \over {500}} = {1 \over 5} \Rightarrow W = {6 \over 5} = 1.2\,kcal$$
