Quizplus · Accepted Answer

I. Liquids have more entropy than their solids, as the molecules are more disordered in the liquid phase.
II. Solutions have more entropy than the solids dissolved, as the solute molecules add to the disorder of the solution.
III. Gases and their liquids do not have equal entropy, as gases are more disordered than their liquid counterparts.
IV. Gases actually have more entropy than their corresponding solids, as the molecules in gases are free to move in more directions and have more degrees of freedom.
V. Entropy of a substance increases as its temperature increases, as the molecules have more kinetic energy and are more disordered.
