a. dew.
b. fog.
c. clouds.
d. all of the above

1. what is the term for the temperature at which water vapor condenses out of the air and forms liquid water?

a. dew point
b. melting point
c. freezing point
d. boiling point

Explanation:

Question 7

For a liquid molecule to evaporate (convert to vapor), it needs to be near the surface (to escape), moving in the proper direction (towards the surface or away from the bulk), and highly energized (to overcome intermolecular forces). So all conditions (a, b, c) are required.

The temperature at which water condenses out of air is defined as the dew point. Dew drops are the condensed water, dew is the phenomenon, but the term for the temperature is dew point.

Condensation is the process of gas turning to liquid. Dew forms when water vapor condenses on cool surfaces, fog is condensation of water vapor near the ground, and clouds form when water vapor condenses in the atmosphere. So all (a, b, c) are formed by condensation.

Answer:

d. All of the above
