Priya took a soil in a boiling tube and corked it with cotton. Then she heated the boiling tube on a spirited lamp. After some time she observed tiny drops of water droplets inside the boiling tube. What should be Priya's inference?
Soil contains air, water, minerals and organic matter. The moisture in the soil is nothing but the water content of the soil. Priya's inference should be that the soil taken by her contains moisture as tiny water droplets are appearing on the wall of the boiling tube.
