Sagot :

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
