Alcohol and water are both liquids that can evaporate, or turn into a gas, at room temperature. However, alcohol tends to evaporate faster than water under most circumstances. There are several reasons why this is the case.

One reason why alcohol evaporates faster than water is because it has a lower molecular weight than water. The molecules in alcohol are lighter and less dense than the molecules in water, which makes it easier for alcohol molecules to escape from the liquid and turn into a gas.

Another reason why alcohol evaporates faster than water is because it has a lower boiling point. The boiling point of a substance is the temperature at which it changes from a liquid to a gas. Alcohol has a lower boiling point than water, which means that it requires less heat to turn into a gas. As a result, alcohol is more likely to evaporate at room temperature than water.

In addition, alcohol has a higher vapor pressure than water. Vapor pressure is the pressure exerted by a vapor when it is in equilibrium with its liquid form. A substance with a higher vapor pressure is more likely to evaporate at a given temperature. Alcohol has a higher vapor pressure than water, which means that it is more likely to evaporate at room temperature.

Finally, alcohol is more volatile than water, which means that it has a higher tendency to evaporate. Volatility is a measure of how easily a substance turns into a gas at a given temperature. Alcohol is more volatile than water, which means that it is more likely to evaporate at room temperature.

In conclusion, alcohol evaporates faster than water because it has a lower molecular weight, a lower boiling point, a higher vapor pressure, and higher volatility than water. These properties make it easier for alcohol molecules to escape from the liquid and turn into a gas at room temperature.
