in a carnot cycle the gas expands adiabatically from 200 degrees to 500 degrees. what is the efficecy? and what is the entropy change of the gas during the expansion?(adsbygoogle = window.adsbygoogle || []).push({});

sorry - i got the efficiency to be: 38.8%

however I am unsure how to work out the entropy chance? any hints???
