Question

give 2 examples of a form of condensation at higher elevation​

Answer 1

Answer:

• The transformation of water vapour into water is called condensation.
• Condensation is caused by the loss of heat (latent heat of condensation, opposite of latent heat of vaporization).
• When moist air is cooled, it may reach a level when its capacity to hold water vapour ceases (Saturation Point = 100% Relative Humidity = Dew Point reached). Then, the excess water vapour condenses into liquid form. If it directly condenses into solid form, it is known as sublimation.
• In free air, condensation results from cooling around very small particles termed as hygroscopic condensation nuclei. Particles of dust, smoke, pollen and salt from the ocean are particularly good nuclei because they absorb water.
• Condensation also takes place when the moist air comes in contact with some colder object and it may also take place when the temperature is close to the dew point.
• Condensation, therefore, depends upon the amount of cooling and the relative humidity of the air.
• Condensation takes place:
• 1. when the temperature of the air is reduced to dew point with its volume remaining constant (adiabatically),
• 2. when both the volume and the temperature are reduced,
• 3. when moisture is added to the air through evaporation,
• After condensation the water vapour or the moisture in the atmosphere takes one of the following forms — dew, frost, fog and clouds.
• Condensation takes place when the dew point is lower than the freezing point as well as higher than the freezing point.
