Homework Statement
433J of heat is extracted from a massive object at 0[tex]\circ[/tex]C while rejecting heat to a hot reservoir at 19[tex]\circ[/tex]C.
What minimum amount of work will accomplish this? Answer in units of J.
Homework Equations
COP= Qc/(Qh-Qc) = Tc/(Th-Tc)
The Attempt at a Solution
433J * 273.15K/(292.15K-273.15K)=6224.944 joules
