- Describe the classification of evaporators. Explain the factors that affect evaporationprocess. 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…
- When a meteorologist reports precipitation in the weather forecast, this is usually associated with a low-pressure system. 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.Substance X is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature.

- 18. Water contamination is a significant issue that can have serious consequences for humans and the environment. a. Complete the following chart with information related to water contamination. Source of Contamination Specific Chemical Pollutants Possible Effects on Health of Humans and the EnvironmentDirection: 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?The vapor pressure of liquid bromoethane, C2H5Br, is 100. mm Hg at 263 K. A 0.169 g sample of liquid C2H5Br is placed in a closed, evacuated 350. mL container at a temperature of 263 K. Assuming that the temperature remains constant, will all of the liquid evaporate? Yes or No. What will the pressure on the container be when the equilibrium is reached? ___ mm Hg. The vapor pressure of liquid butanol, C6H9OH, is 100 mm Hg at 343 K. a sample of C4H9OH is placed in a closed, evacuated 543 mL container at a temperature of 343 K. It is found that all of the C4H9OH is in the vapor phase and that the pressure is 68.0 mm Hg. If the volume of the container is reduced to 354 mL at a constant temperature, which of the following statements are correct? Choose all that apply: A) No condensation will occur B) Only butanol vapor will be present C) Some of the vapor initially present will condense D) The pressure in the container will be 104 mm Hg E) Liquid butanol will be present
