A water molecule at the surface contains enough kinetic activity to enter the vapor state. This is the definition of which of the following?
a. Evaporation c. The boiling point
b. Vaporization d. The critical point
ANS: A
Evaporation occurs when liquid molecules near the surface contain enough kinetic energy to break free and enter a vapor state without the addition of heat. Vaporization is the energy re-quired to vaporize a liquid. The boiling point is when the water is heated to a point at which molecules leave the liquid state and produce water vapor.
