Question

Quizplus · Accepted Answer

The freezing point is the temperature at which a substance changes from a liquid phase to a solid phase. The boiling point is the temperature at which a substance changes from a liquid phase to a gas phase. Generally, substances with higher boiling points also have higher freezing points, but the freezing point is always lower than the boiling point. Therefore, option B is correct. The heat of fusion and heat of vaporization are not directly related to the freezing point of a substance, so options C and D are incorrect.
