. On heating the soil sample in the boiling tube what will you observe?

(a) It starts boiling                      

(b) No change in the sample

(c) Water vapours condense on the cooler inner walls of upper part of boiling tube   

(d) Soil particles start vaporizing


Best Answer


When the soil sample is heated in a test tube water droplets are seen on the cooler parts of the test tube. This simply shows that soil has moisture and on heating this moisture or water evaporates into water vapours which condenses on the cooler parts of the test tube and are seen as water droplets.
