Question

Which process is the likely cause of the water droplets observed on the inner upper surface of the bottle left outside in the sun?

A) Condensation
B) Evaporation
C) Sublimation
D) Transpiration

Answer 1

The water droplets on the inner surface of the bottle are most likely caused by condensation, which occurs when water vapor cools and returns to liquid form.

Step-by-step explanation:

The likely cause of water droplets observed on the inner upper surface of a bottle left outside in the sun is condensation. When the water vapor inside the bottle cools down upon coming into contact with the cooler surface of the bottle's upper inner side, it changes back into a liquid form, resulting in condensation. This process can be observed when warm, moist air inside a container meets a colder surface, causing the vapor to lose energy and form water droplets.

Evaporation is the process by which liquid water turns into water vapor below its boiling point, and it usually occurs when the sun heats the water, giving molecules enough energy to escape into the atmosphere. In a closed environment, such as a bottle, the water vapor may not escape, leading some of it to condense back into liquid form when it cools down.
