Prove that the following two statements of the second law are equivalent (each one can be derived from the other):
(a) “It is impossible for heat to flow spontaneously from a colder to a warmer body without causing other changes”
(b) “It is impossible to convert all the heat taken from a body of uniform temperature into work without causing other changes”
(hint: one can prove the equivalence of the two statements by showing that if one is violated then so is the other and vice versa.)
The attempt at a solution
I have no idea how to approach this question mathematically...
