1.	Find the possible efficiency of a cycle working between `27^(@)C` and `127^(@)C`.
Answer» We cannot find efficiency fo a cycle until we have complete information about all processes involved but we can find maximum efficiency between given temperature which corresponds Carnot cycle. `implieseta_(max)=1-(T_(L))/(T_(H))=1-(300)/(400)=(1)/(4)` `implieseta_(max)=25%` Hence `eta` of the cycle `le25%`.
