A heat engine absorbs heat Q_(1) at temperature T_(1) and Q_(2) at temperature T_(2) . Work done by the engine is (Q_(1)+Q_(2)) . This data:

Answer»

Violates `I^(ST)` law of thermodynamics
Violates `I^(st)` law of thermodynamics if `Q_(1)` is -ve
Violates `I^(st)` law of thermodynamics if `Q_(2)` is -ve
Does not violate `I^(st)` law of thermodynamics

SOLUTION :It does not violates the FIRST law of thermodynamics but violates the II law of thermodynamics.
