प्रश्न
Explain, why do sandy soils, get heated up quickly as compared to wet soils?
Advertisements
उत्तर
The specific heat capacity of sand is about five times less than water. Thus,when sun shines equally on sandy soil and wet soil, the sandy soil gets heated up rapidly as compared to wet soil. It is because water absorbs large amount of heat energy, but its temperature does not rise sufficiently.
