Calculate the slope of the line obtained deduce its sense

He sandals were out in the sun so the got hotter. which is why her feet felt hot.

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.

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.
