Atoms contain subatomic particles called protons and neutrons. When these protons and neutrons split, a lot of energy released

Transfer of electrons. hope it !

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.

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.

Well it depends on the object or substance
