UPSC Civil Services Model Paper 1

● The transformation of water vapour into water is called condensation.
● Condensation is caused by the loss of heat.
● Condensation takes place when ◦ the temperature of the air is dropped down to dew point with its volume remaining constant.
◦ both the volume and temperature are reduced.
◦ moisture is added to the air through evaporation.
● The most favourable condition for condensation is the decrease in air temperature.
