NCERT Class 11 Physical Geography Chapter 11: Water in the Atmosphere | English

Dr. Manishika Jain explains the NCERT Class 11 Geography chapter 11: Water in Atmosphere

Water Vapour is 0-4%
Water as solid, liquid or gas
Moisture by evaporation or transpiration
Continuous exchange b/w evaporation, transpiration, condensation and precipitation
Absolute Humidity - actual amount of the water vapour present in the atmosphere (gm/cm3) – ability to hold water depends on temperature
Relative Humidity - % moisture as compared to full capacity; greater over the oceans and least over the continents
Saturated Air – air containing moisture to its full capacity at given temperature
Dew point – temperature at which saturation occurs in the sample of air
Evaporation – water from liquid to gas
Latent Heat of Vaporization – Temperature at which water starts evaporating
Increase in temperature increases water absorption and retention capacity of the given parcel of air
Condensation – transformation of water vapor to water (by loss of heat). In free air, condensation results from cooling around very small particles termed as hygroscopic condensation nuclei or when the moist air comes in contact with some colder object. It is influenced by temperature, pressure, volume of air and humidity.
