In an open system ,the increase in evaporation causes the decrease in temperature of the liquid.
The evaporation of water increases under the following conditions :
(a) increase in temperature, decrease in surface area
(b) increase in surface area, decrease in temperature
(c) increase in surface area, rise in temperature
(d) increase in temperature, increase in surface area, addition of common salt
Decrease in humidity at a given temperature increases the rate of evaporation.
Fill in the blanks.
(a) To prevent the evaporation of water from lakes ………… is sprayed on the surface of the water.
(b) An increase in temperature causes ………… evaporation.
(c) The proportion of dissolved ………… in polluted water is low.
