Question

removing energy from liquid water causes it to become ice. similarly, removing energy from air, causes it to _____.

a. evaporate

b. condense

Explanation:

When energy is removed from a substance, it typically undergoes a phase change to a more ordered (lower - energy) state. Removing energy from liquid water (a liquid) causes it to become ice (a solid), which is a phase change from liquid to solid (freezing). Air contains water vapor (a gas). Removing energy from water vapor in the air causes it to change from gas to liquid, which is condensation. Evaporation is the process of a liquid turning into a gas, which requires energy input, so option a is incorrect.

Answer:

b. condense
