Asealed container full of air is placed on top of a block of dry ice (frozen carbon dioxide). in the following questions you will use your understanding of the behavior of molecules to describe what happens as you cool the air. which of the following best describes the behavior of the air molecules?

The answer is orbit around nucleus

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
