Exercise 1.26 A 5.0 lb box of grass seed will seed 2500 ft2 of
lawn. = Express this coverage in m^2/kg

K= m^2/kg

Biased means unfair but that's all ik

The relationship of both of them

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.
