Question

lesson 15 - water cycle
where did the water droplets on this cold mug come from?
(1 point)
○ refrigerator
○ dishwasher
○ water vapor in the air
○ water inside mug

Explanation:

The water droplets on a cold mug form due to condensation. When the mug is cold, the water vapor in the surrounding air (which is warm and holds water vapor) comes into contact with the cold surface of the mug. The water vapor then cools down and condenses into liquid water droplets. The refrigerator is where the mug might have been cooled but not the source of the droplets, the dishwasher is for cleaning and not related to this condensation, and the water inside the mug wouldn't form droplets on the outer surface in this way.

Answer:

C. water vapor in the air
