What do water, acetone, and alcohol become as they evaporate?

As water, acetone, and alcohol evaporate, they transform from their liquid state into vapors. This process occurs when the molecules of the liquid gain enough energy to break free from the surface and disperse into the air. The term "vapors" specifically refers to the gaseous state of these substances when they transition from a liquid form during evaporation.

While the other terms might suggest different phenomena, they are not the most accurate descriptions of what happens to these liquids upon evaporation. Liquid refers to their original state before evaporation, aerosol relates to tiny particles suspended in a gas, and fog is a visible mass of condensed water droplets that forms at ground level. In contrast, vapors directly relate to the gaseous state that arises from the evaporation of liquids, making it the correct answer in this context.
