Q.
A heat engine absorbs heat $Q_{1}$ at temperature $T_{1}$ and heat $Q_{2}$ at temperature $T_{2}$, work done by the engine is $(Q_{1} + Q_{2})$ this data
A) Violates 1st law of thermodynamics
B) Violates 1st law of thermodynamics if $a_{1}$ is $–$ve
C) Violates 1st law of thermodynamics if $a_{2}$ is $-$ve
D) Does not violates 1st law of thermodynamics
Explanation
(d)
It does not violate the first law of thermodynamics but violates the II law of thermodynamics
