Which of the following is/are TRUE about boiling?
I.Boiling a liquid requires more energy than does evaporating it.
II.A liquid's boiling point varies with the atmospheric pressure.
III.The greater the ambient pressure, the lower is the boiling point.

Question

Quizplus · Accepted Answer

Statement i is true because boiling requires the addition of heat energy to overcome the intermolecular forces that hold the liquid together. Statement II is true because the boiling point of a liquid is directly proportional to the atmospheric pressure above the liquid. So, if the pressure changes, so does the boiling point. Statement III is also true due to statement II, as the higher the external pressure, the higher is the boiling point.
