An ideal heat engine operates with an input temperature of 327C and an exhaust temperature
of 27C. If the input temperature is lowered to 227C, by how much must be the exhaust
temperature be lowered to maintain the same eciency?Im using η= 1-(tc/th) that works out to 1-(300k/600k) = 0.5 then took 227c = 500k*0.5 =250 ∴ 1-(250k/500k)=0.5
So i come to -23c but that dose not seem right if someone can help me here would be a big help thanks
