Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
My glass of ice water is sitting in the sun and has droplets of water on the outside of the glass. What is happening?
A
condensation
B
evaporation
C
melting
D
freezing
Explanation: 

Detailed explanation-1: -Condensation can also produce water droplets on the outside of soda cans or glasses of cold water. When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can.

Detailed explanation-2: -The water vapour present in the air comes in contact with cold surface of the glass, loses its energy and gets converted into droplets of water.

Detailed explanation-3: -Since during condensation the water vapours (gas) are converted to water (liquid), so, it is a physical change.

Detailed explanation-4: -Condensation is the process by which water vapor in the air is changed into liquid water; it’s the opposite of evaporation. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.
