Irrigation is the artificial process of applying controlled amounts of water to land to assist in production of crops. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
The specific heat means the heat absorbed when 1 g of the compound increase 1 ℃. So the specific heat is 41.71/(18.69*17)=0.131 J/(g*k).
<span>Oxygen-16 atomic number is 8 so it has 8 protons. Its atomic weight is 16 so 16-8 = 8 neutrons.

Because the molecules are more closely spaced, the solid occupies less space than the same substance when it is in a gaseous state.
It happens so because,
we know that evaporation is a surface phenomenon. If surface area is increased, the rate of evaporation increases. That's why when we pour hot water in a plate it cools faster.
