When a sugar cube dissolves in a cup of coffee (an endothermic process), entropy changes of the sugar plus water, the surroundings, and the universe respectively are...
A. negative, positive, positive
B. positive, negative, negative
C. positive, positive, positive
D. None of these are correct.
E. negative, negative, negative

Answer :

positive, negative, positive are the entropy changes of the sugar plus water, the surroundings and the universe respectively

∆s of system is positive because it is becoming more disordered as it becomes a mixture as sugar dissolves.

∆s of surroundings is negative because it is giving heat to system (losing heat) so it is becoming more ordered.

∆s of the universe is positive because the reaction is spontaneous-- second law of thermo.

In spontaneous changes, the universe tends toward a state of greater disorder
