- Define evaporation and explain the theory, mechanism and applications ofevaporation. Please answer at your own easy words.How does hydraulic fracturing differ from previously used techniques for the recovery of natural gas from the earth?So here are a series of experiments:1. A balloon was held against a wall. When it was released, the balloon fell to the floor. 2. A balloon was rubbed with a piece of wool and again held against a wall. This time, whenthe balloon was released it stuck to the wall. 3. A hole was poked in the bottom of a plastic cup. The cup was filled with water, and thewater was allowed to drain out through the hole in the bottom of the cup. While the water wasrunning out the bottom of the cup, a balloon was held near the stream of water. The watercontinued to fall straight down. 4. The previous demonstration was repeated, except this time the balloon was rubbed withwool before it was held near the stream of water. This time, the stream of water was drawntoward the balloon instead of falling straight down. Please explain all of the above. Also please show that you have a really good understanding ofthe laws of electrostatics and the structure of atoms as you do so, and use each of the following terms…

Go through the following activity to explain why precipitation would be associated with a low atmospheric pressure. Air that is saturated or contains water vapor will have more water and [ Select ] v dry air in the overall mixture compared to dry air. This causes the overall density of the air to [ Select ] V. The air will be [ Select ] dense than dry air and the atmospheric pressure will be [Select] than dry air.

Source of Contamination Specific Chemical Pollutants Possible Effects on Health of Humans and the EnvironmentCorrelate solidification with crystallization(Explanation needed).Direction: Provide an explanation for the phenomenon Based on the kinetic molecular model, solids usually have higher densities compared to liquids. However, ice, a solid form of H2O floats on liquid water which means ice is less dense than water. What do you think is the reason for this phenomenon? What is the biological significance of this concept?
