Answer:
Evaporation is a physical process by which a liquid transforms into a gas or vapor phase. It occurs when the temperature of the liquid is increased, which causes the kinetic energy of the liquid molecules to increase. This increased kinetic energy allows some of the liquid molecules to break free from the surface of the liquid and enter the gas or vapor phase.
At the molecular level, a liquid is made up of molecules that are held together by intermolecular forces. These forces are responsible for keeping the molecules in close proximity to one another, creating a cohesive liquid state. However, not all of the molecules in a liquid have the same energy. Some molecules have more energy than others due to random collisions with other molecules or from absorbing heat.
As the temperature of the liquid increases, the average kinetic energy of the molecules also increases. This means that some of the molecules in the liquid will have enough energy to overcome the intermolecular forces that hold them in the liquid state. These molecules will break free from the surface of the liquid and enter the gas or vapor phase, a process known as evaporation.
The molecules that escape from the liquid during evaporation do not do so randomly. Instead, the molecules that have the highest kinetic energy are the most likely to escape, as they have enough energy to overcome the intermolecular forces holding them in the liquid state. This means that the molecules that are left behind in the liquid have a lower average kinetic energy than the molecules that have escaped. As a result, the liquid's temperature decreases as evaporation occurs, as the higher energy molecules are removed from the system.
Explanation:
In summary, the escape of molecules during evaporation is the result of an increase in the average kinetic energy of the liquid molecules due to heating. The molecules with the highest kinetic energy overcome the intermolecular forces that hold them in the liquid state, allowing them to escape and enter the gas or vapor phase. This process continues until the liquid is completely evaporated or until the temperature of the liquid reaches equilibrium with its surroundings.

Explanation:
Based on your reading of the following passage, what should be done with older buildings to reduce the danger from earthquakes?
There is no more important factor in reducing a community’s risk from an earthquake than the adoption and enforcement of up-to-date building codes. Evaluating older buildings and retrofitting structural and nonstructural components also are critical steps. To survive and remain resilient, communities should also strengthen their core infrastructure and critical facilities so that these can withstand an earthquake or other disaster and continue to provide essential services.

describe four precautions and the reasons why they must be adhered to when conducting the compression test
The precautions to be followed when conducting a compression test are:
Warm up the engine to its normal operating temperature before the test.Disable the ignition system to prevent the engine from starting during the test.Remove all spark plugs from the engine before conducting the test.Keep the throttle wide open (fully depressed) during the compression test.What is compression testWhile doing the compression test, it is very important to keep the throttle fully open. This action lets a lot of air go into the engine, which makes the pressure inside the engine higher. If you keep the throttle open, it stops any pressure from building up which could mess up the test results.
Following these precautions when doing a compression test keeps the person doing the test safe, stops any harm to the engine, and gives accurate information for figuring out the engine's condition. Compression tests are important tests that help mechanics find problems with engine parts like valves, piston rings, and cylinder heads. This helps them fix the issues better.
