Evaporation is part of the water cycle and is the process of a liquid becoming a gas or vapor.
For evaporation to work, there has to be some sort of heat from the surface. This heat is known as <span>latent heat. Evaporating water removes surface heat. By removing the surface heat, it lowers the temperatures and water levels, whether it's on land or a body of water.
The only reason it doesn't build and stay in the atmosphere is because of condensation and precipitation.

Answer: 4 x 10 ∧-2 moles of nitrogen.
Explanation:
The chemical formular for quinine is ; C20 H24 N2 O2
As can be seen from the chemical formular;
1 mole of quinine contains 2 moles of Nitrogen
Thus; 2.0 x 10 ∧-2 moles of quinine would contain
2.0 x 10 ∧-2 x 2 = 4 x 10 ∧-2 moles of nitrogen.
Therefore 4 x 10 ∧-2 moles of nitrogen are in 2.0×10−2mole of quinine
