An engine operating between 150^(@)C and 25^(@)C takes 500 J heat from – InterviewSolution

1.	An engine operating between 150^(@)C and 25^(@)C takes 500 J heat from a higher temperature reservoir if there are no frictional losses, then work done by engine is
Answer» 147.7 J 157.75 J 165.85 J 169.95 J Solution :`T_(2)=150+273=423 K , T_(1)=25+273 = 298 K` Q=500 J `(W)/(Q)=(T_(2)-T_(1))/(T_(2)), W=500((423-298)/(423))=147.7 J`.
