Consider a pure crystalline solid that is heated from absolute zero to a temperature above the boiling point of the liquid.Which of the following processes produces the greatest increase in the entropy of the substance?

Question

The process that produces the greatest increase in entropy is the one that involves a transition from a more ordered state to a more disordered state. Within the given options, the highest increase in entropy occurs when the liquid is vaporized, as it involves a transition from a more ordered liquid phase to a more disordered gas phase. The other options involve heating the substance, but this does not necessarily lead to an increase in entropy. For example, heating the solid or liquid may cause the atoms/molecules to vibrate more, but they would still be in a relatively ordered state. Therefore, option E, evaporating the liquid, is the correct choice.
