At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature, the faster these particles of matter move.
If dichloromethane is swapped out and ethyl acetate is used in its place, the extracts then obtained would be highly anti-radical and would be more efficient than dichloromethane.
Since "like dissolves like," ethyl acetate is a polar molecule that works well as a solvent to extract the polar caffeine molecules from coffee beans. The ethyl acetate molecules bind to the caffeine molecules, which then move through the bean cells' cell membranes. After all, the ethanol:water (1:1) solvent combination has been demonstrated to be the best for recovering catechins and delivering extracts with the highest antiradical activity.
Dichloromethane is a volatile colourless liquid used as an organic solvent in many industries. One of its main application is that it used to extract caffeine because of its highly effective solvent nature. Because DCM is a non-polar solvent and caffeine is readily soluble in DCM, it can easily be extracted without losing its aroma.

Because it was built on sand and some of it sunk, and changed due to erosion and weathering of the land
The answer would be C. The disillusionment of people following WW1.
Answer: in a move to protect the economy from the overvalued stock market,made successive interest rate increases.Using the stock market as an unofficial benchmark,a recession would have begun in March 2000 when the NASDAQ crashed.
Explanation:the drive of housing bubble cause the recession that began in the mid 2000s.the effect of that made the NASDAQ crash
