Question

when water vapor cools and turns back into liquid droplets, the process is called
○ condensation
○ transpiration
○ freezing
○ evaporation

Explanation:

• Condensation: The process where water vapor (gas) cools and changes into liquid droplets. This matches the description in the question.
• Transpiration: The process of water movement through a plant and its evaporation from aerial parts (like leaves), not related to water vapor turning to liquid droplets.
• Freezing: The process of a liquid turning into a solid (ice), not gas to liquid.
• Evaporation: The process of liquid water turning into water vapor (gas), which is the opposite of what's described.

Answer:

A. Condensation
