Question

The drops of water that appears on the outside of a glass of cold juice on a warm day is an example of which of the following phase change processes?

• A. Evaporation
• B. Condensation
• C. Deposition
• D. Solidification

Answer 1

The correct option is B Condensation

$\bullet$ Conversion of vapor into liquid water is called condensation. Condensation is the reverse of vaporization i.e. change in the physical state of a substance from a gaseous state to a liquid.
$\bullet$ Here, when water vapour present in the air comes in contact with the cooler surface of the glass then vapour gets converted in to liquid with the release of the energy.
