Question

Due to which of the following phase change process water droplets are seen on the outer surface of a glass containing ice-cold water?

• A. Vaporization
• B. Condensation
• C. Sublimation
• D. Fusion

Answer 1

The correct option is B

Condensation

The air around the container consists of water vapor which accounts to humidity. When the water vapor comes in contact with the outer surface of glass containing ice cold water there is a change in physical state of water vapor to water in liquid phase due to lower temperature and condensation, hence accounting to the water droplets on the outer surface of a tumbler or glass containing ice cold water.
