It causes your body to remove fluids from your blood through your renal system, which includes the kidneys, ureters, and bladder, at a much quicker rate than other liquids. The author states that the evaporation rate of alcohol is also affected by the amount of surface area that is exposed to the air. This is because it has a very low boiling point, meaning that it turns into a gas at relatively low temperatures. A larger surface area means that more alcohol molecules are exposed to the air, which speeds up the evaporation process. In fact, isopropyl alcohol has a very low boiling point, which is why it is often used in things like cleaning products and hand sanitizers. Its popularity is due in part to its relatively low cost and its ability to dissolve a wide range of materials. But what if you've only had a few sips and want to save the rest for later?
