How Fast Does Alcohol Evaporate [At Room Temperature and When Boiling]?

Last Updated on May 13, 2022

Alcohol evaporates very slowly from a glass or bottle at room temperature. How much alcohol does it take to fill a glass?

The amount of alcohol in a drink depends on its volume and density. If you pour a shot of whiskey into a glass, it will only contain around 0.5% alcohol. This means that it takes around 50 shots of whiskey to equal one standard drink.

A standard drink contains approximately 12 grams of pure ethanol (alcohol). This means that a single shot of whiskey has roughly 4 grams of alcohol. Therefore, it would take around 500 shots of whiskey to equal the same amount of alcohol found in one standard drink.

Does ethyl alcohol expire?

Yes, if you leave an open container of alcoholic beverages out for too long, they can spoil. The best way to keep your drinks fresh is to store them in a cool place away from direct sunlight. Store bottles and cans upright with their necks pointing down.

If you’re planning on drinking a lot of alcohol over the course of a few days, you should also consider storing your drinks in the fridge. This will slow down evaporation so that you don’t have to worry about spoiling your drinks by accident.

What are the different types of alcohol?

Alcohol comes in many forms: beer, wine, spirits, liqueurs, etc. Each type has unique characteristics and uses. For example, some people prefer red wines while others enjoy white wines. Some people like strong liquor while others prefer light liquors.

Alcoholic beverages come in all shapes, sizes, and colors. They range from clear liquids to cloudy ones. Some are sweetened; others aren’t. Some are served chilled; others are served hot.

What happens when I drink alcohol?

When you consume alcohol, it travels through your stomach and then enters your bloodstream. Your body breaks down the alcohol into water and carbon dioxide. Carbon dioxide is what makes you burp after consuming alcohol.

Your liver metabolizes the alcohol into various compounds called metabolites. These include acetaldehyde, which causes hangovers, and acetic acid, which gives vinegar its sour taste.

Your brain processes the alcohol as well. It slows down your reaction time and reduces coordination. You may feel more relaxed but this feeling doesn’t last long.

Does ethyl alcohol evaporate faster than isopropyl alcohol?

No, both ethyl alcohol and isopropyl alcohol evaporate at the same rate. However, isopropyl alcohol is less toxic than ethyl alcohol.

Why do we need to know how fast alcohol evaporates?

Knowing how fast alcohol evaporates helps us determine how much alcohol is left in our drinks. When we add alcohol to a liquid, we want to make sure that there is enough alcohol left to get drunk.

For example, if you mix two parts vodka with one part juice, you’ll end up with three parts vodka. You won’t be able to tell whether or not you had a full bottle of vodka because you didn’t measure the exact amount of alcohol.

The same thing applies to mixing alcohol with other ingredients such as soda or tonic water. If you add alcohol to these products without measuring first, you could end up with a beverage that tastes great but isn’t very intoxicating.

Does alcohol evaporate in air?

Yes, alcohol does evaporate in air. But it takes longer than alcohol evaporating in water.

How long does it take for pure alcohol to evaporate?

What happens when alcohol is exposed to air?

Alcohol molecules combine with oxygen in the air. This forms an oxide layer over the surface of the alcohol molecule.

If you expose alcohol to air for a long period of time, the oxide layer will grow thicker. Eventually, the oxide layer becomes so thick that it prevents any further evaporation.

When alcohol is exposed to air for a short period of time, the alcohol molecules don’t have time to form an oxide layer. As a result, they evaporate easily.

How long does beer last?

Beer lasts longer than wine because it has less alcohol content. Beer has between 5 and 8 percent alcohol by volume. Wine has 12-14 percent.

The average bottle of beer holds about 24 ounces. One ounce of beer equals 0.24 liters.

An average bottle of wine holds about half as much. A half-bottle of wine equals 0.12 liters.

Do you ever wonder if alcohol evaporates faster at room temperature or when boiling?
There’s no doubt that alcohol evaporates faster at higher temperatures.
However, there are several factors that affect evaporation rates.
In this blog I’m going to explain you how much alcohol evaporates at different temperatures.


Alcohol evaporates very quickly from liquid form into gas form. At room temperature, alcohol evaporates at a rate of about 1 gram per minute. This rate doubles when the alcohol is heated to 100 degrees Celsius 212 degrees Fahrenheit. Boiling When alcohol is heated to 212 degrees F 100 degrees C, it turns directly into vapor. As soon as the alcohol reaches 212 degrees F, it immediately changes into vapor. It takes only a matter of seconds for the alcohol to change from liquid to vapor.

Boiling Point

Boiling point is the temperature at which a substance changes from solid to liquid state. Water boils at 100 degrees Celsius 212 degrees F because it becomes a gas at that temperature. Alcohol boils at 78 degrees Celsius 167 degrees F. Evaporating

Other Factors That Affect Evaporation

Temperature, humidity and wind speed affect evaporation. Evaporation rate depends upon the surface area of the object being evaporated. A larger surface area allows more air molecules to pass through the surface and thus reduces the vapor pressure. This results in lower vapor pressure and hence higher vapor concentration.


Surface area is the total area of the surface of the object. It is measured in square meters m2. Humidity is the percentage of moisture in the air. It is measured in percent %. For example, if the humidity is 50%, it means that half of the air molecules in the atmosphere are water vapor.

Wind Speed

Wind speed is the rate of wind flow past a given point. It is measured in knots 1 knot = 1 nautical mile per hour. A wind gauge measures the wind speed. Air Temperature

Alcohol Evaporating From Drinks

Alcohol evaporates from drinks because alcohol molecules are lighter than air molecules. As alcohol molecules move away from the liquid surface, they become less dense than the surrounding air molecules. This allows the alcohol molecules to float upward until they reach equilibrium with the surrounding air. At this point, the alcohol molecules no longer exert any force on the air molecules around them, and the air molecules begin to fall back toward the liquid surface. Aerosol Formation

Cooking With Alcohol

Cooking with alcohol is not recommended. It is very dangerous and can lead to serious health problems. Drinking alcohol while cooking is especially dangerous because alcohol can interfere with the taste of food. Cooking with alcohol can also damage the flavor of the food being cooked.

Alcohol Evaporation

Alcohol evaporates from the surface of liquid into air. This process is called evaporation. As alcohol evaporates, it leaves behind a residue of water. The amount of water left depends on how much alcohol is present. In other words, the more alcohol, the less water remains.

Does ethyl alcohol expire?

Ethanol ethyl alcohol is a colorless flammable liquid used as a solvent, fuel additive, and antifreeze. It is produced commercially by fermentation of sugars derived from corn, sugar cane, molasses, and potatoes. Ethanol is used primarily as a fuel additive in gasoline and as a component of many industrial solvents. It is also used as a food preservative and flavoring agent. Ethanol is a common ingredient in alcoholic beverages such as beer, wine, and liquor. Ethanol is not poisonous; however, it is toxic if ingested in large quantities. Ethanol is absorbed rapidly into the bloodstream after ingestion. Symptoms of ethanol poisoning include headache, nausea, vomiting, dizziness, drowsiness, blurred vision, slurred speech, confusion, seizures, coma, and death.

Does ethyl alcohol evaporate faster than isopropyl alcohol?

Isopropyl alcohol IPA is a clear, colorless, volatile liquid with a strong odor. IPA is widely used as a solvent, especially in paint thinners, nail polish removers, and other cleaning products. Isopropyl alcohol is also used as a disinfectant and preservative in cosmetics and pharmaceuticals. Isopropyl Alcohol is a type of organic compound containing two carbon atoms bonded together via an oxygen atom. It is a colorless, volatile liquid that is miscible with water. It is a clear, color free, non-flammable liquid that is highly flammable when mixed with air. It is used as a solvent, particularly in paints, lacquers, varnishes, and resins. It is also used in some types of glues, adhesives, and sealants.

Does alcohol evaporate in air?

Yes, pure ethanol evaporates at room temperature. It evaporates at a rate of about 2.2 grams per hour at room temperature. How fast does pure alcohol evaporate at higher temperatures? Answer: At higher temperatures, pure ethanol evaporates faster. At 100 degrees Celsius 212 degrees Fahrenheit, pure ethanol evaporates at a rate between 3.3 and 4.4 grams per hour.

How long does it take for pure alcohol to evaporate?

Pure ethanol alcohol evaporates very quickly. Pure ethanol evaporates from liquid solutions at a rate of about 0.5% per minute. This means that 1 gram of ethanol evaporates approximately every 5 minutes.

Does air evaporate alcohol?

Yes, air does evaporate alcohol. Alcohol evaporates easily because it is a volatile substance. Volatile substances are those that readily give off vapors. These vapors are gases. Gases are substances that have no definite shape or structure. They are usually colorless, odorless, tasteless, and invisible. Gases are formed when substances lose their bonds with other molecules. Molecules are the smallest units of any substance. Molecules bond together to form compounds. Compounds are composed of two or more different types of atoms bonded together. Atoms are the building blocks of all matter. Air contains oxygen O2 and nitrogen N2. Oxygen is an element found in the atmosphere. It is a colorless, odorless gas that is essential to life. Nitrogen is an inert gas that is not harmful to humans.

Does pure alcohol evaporate at room temperature?

Alcohol evaporates easily from liquid form into gas form. This process is called evaporation. Evaporation is the conversion of a substance from a solid, liquid, or gaseous state to another state. In other words, evaporation is the transition of a substance from a liquid to a vapor. Evaporation is the result of a change in phase solid, liquid, or gas of a substance. A substance changes phase when it undergoes a physical transformation. For example, ice melts into water, which is a liquid. Water freezes into ice, which is a solid. When a substance undergoes a phase change, it loses mass. Mass is defined as the quantity of matter contained within a given volume. As a substance loses mass, it becomes lighter. Therefore, if a substance loses mass, its density decreases. Density is a measure of how heavy a substance is compared to water.

What happens when alcohol is exposed to air?

Alcohol evaporates very quickly in air. It takes about 2 hours for 1/2 gallon of 80 proof 40% ABV alcohol to evaporate completely. If you put alcohol in hot water, it will not evaporate until the water cools down.

How long does it take for isopropyl alcohol to evaporate?

Isopropyl Alcohol IPA evaporates slowly because it contains a higher percentage of water than ethanol. IPA evaporates in approximately 3 days. What happens if I pour alcohol into hot water?

How fast does pure alcohol evaporate?

Pure alcohol evaporates very quickly. It takes about 2 hours for 1 cup of 100 proof whiskey to completely evaporate. This is why people drink it neat straight rather than mixing it with other drinks.
