Set up an experiment to measure gain and loss of heat by water, sand and air.
Set up an experiment to measure gain and loss of heat by water, sand and air.
(i) Take a beaker full of water, a beaker full of soil and a closed bottle containing a thermometer.
(ii) Keep them in bright sunlight for three hours.
(iii) Now, measure the temperature of all three vessels and also take the temperature reading in shade at the same time.
(iv) You will observe that the temperature of the soil and sand is more than that of water in bright sunlight because sand and soil gets heated by solar radiations faster than the water.
(v) Therefore, land would become hot faster than the sea.
(vi) You will also observe that the temperature of air in shade is different from the temperature of soil, sand and water in bright sunlight because of the direct effect of radiations.
