Question

Which of the following statement(s) is/are correct?

• A. Evaporation is not possible at indoor places.
• B. Condensation is the conversion of water vapour into liquid.
• C. The rate of evaporation is dependent on temperature.
• D. Cool vapours in air can be called condensation.

Answer 1

Answer: (B), (C)

The correct options are
B Condensation is the conversion of water vapour into liquid.
C The rate of evaporation is dependent on temperature.

Evaporation is the process by which water changes from liquid state to gaseous state. One of the factors which affect the rate of evaporation is temperature. In dark or shadow regions, evaporation takes place, but the rate of evaporation is slow compared to the region having direct sunlight. Thus, indoor places will have slower evaporation as compared to outdoor places. Condensation of water happens when water vapour cools to such an extent that it becomes liquid.
