Khoxy Posted July 31, 2019 Report Share Posted July 31, 2019 (edited) A heat engine operates between two reservoirs at 300k. During each cycle, it absorbs 200 calories from the high temperature reservoir. Calculate:(a) The maximum efficiency of the system (b) The maximum works the engine can perform in each cycle The problem is giving me tough time because the temperature range doesn't give two figures - it's just 300k. May somebody tip me please! Edited July 31, 2019 by Khoxy Quote Link to comment Share on other sites More sharing options...

Have you tried re-reading the question? Or querying it with the person who set it? Quote Link to comment Share on other sites More sharing options...
Khoxy Posted August 3, 2019 Author Report Share Posted August 3, 2019 Thanks exchemist. The question comes from a well experienced university lecturer. And this is not the first time for him to ask very confusing questions. I don't know what he expects from us. Quote Link to comment Share on other sites More sharing options...
