A thermodynamic process occurs with a heat lost by the system. Does the entropy of
the system necessarily decrease? Why or why not?
a.
Yes.
b. No, because there are other mechanisms to change the entropy.
c. No, because the Second Law of Thermodynamics forbids the decrease in
entropy of a system.
d. No, because heat lost means increase in the entropy.
e. No, because transfer of heat is not related to the entropy change at all.
