MODS close this thread down i figured out the answer myself
A refrigerator has a coefficient of performance of 2.16. Each cycle it absorbs an amount of heat equal to 3.435×104 J from the cold reservoir.
i need to find a) the mechanical energy required each cycle to operate the refrigerator.
b)during each cycle how much heat is discarded to the high temperature reservoir.
e = W/Qh; e=1+(Qc/Qh)
i used the formula in b and apparently it isn't the answer. i also tried using 1-(Qc/Qh) to find Qh. it still didn't work. any other ideas?
thanks
