In a Liquid at a Given Temperature, the Molecules Are

Multiple Choice

In a liquid at a given temperature, the molecules are moving in every direction, some fast, some slowly. Electrical forces of adhesion tend to hold them together. However, occasionally one molecule gains enough energy (as a result of collisions) so that it pulls loose from its neighbors and escapes from the liquid. Which of the following can best be understood in terms of this phenomenon?

A) When you step out of a swimming pool and stand in the wind, you will get colder than you would if you stayed out of the wind.
B) If snow begins to fall when you are skiing, you will feel colder than you did before it started to snow.
C) A hot water bottle will do a better job of keeping you warm than will a rock of the same mass heated to the same temperature.
D) When a large steel suspension bridge is built, gaps are left between the girders.
E) Increasing the atmospheric pressure over a liquid will cause the boiling temperature to decrease.
