Density of ethanol at various temperatures
Ethanol, also known as ethyl alcohol or grain alcohol, is a colorless, flammable liquid with a distinctively pleasant aroma. It is widely used in a variety of products and industries, including beverages, personal care products, cleaning agents, and fuel. One important physical property of ethanol is its density, which is a measure of its mass per unit volume. The density of a substance is influenced by various factors, including temperature. In this essay, we will explore how the density of ethanol changes at different temperatures.
At room temperature (around 20°C or 68°F), the density of ethanol is around 0.789 grams per milliliter (g/mL). This value is relatively consistent across a wide range of temperatures, with only a small change in density observed over a temperature range of 20-30°C (68-86°F). However, at higher temperatures, the density of ethanol begins to decrease significantly.
As the temperature of ethanol increases, the molecules gain more energy and start to move around more vigorously. As a result, the distance between the molecules increases, leading to a decrease in the density of the liquid. This phenomenon is known as thermal expansion. The effect of thermal expansion on the density of ethanol is more pronounced at higher temperatures.
For example, at a temperature of 60°C (140°F), the density of ethanol decreases to about 0.785 g/mL. At 100°C (212°F), the density drops to about 0.780 g/mL. The density continues to decrease as the temperature increases, with a value of about 0.775 g/mL observed at 120°C (248°F).
It is important to note that the density of ethanol is also influenced by its concentration. Ethanol can be mixed with water to form a solution with a lower concentration of ethanol. The density of these solutions is typically lower than the density of pure ethanol, due to the presence of water, which has a lower density than ethanol.
In conclusion, the density of ethanol changes with temperature, with a decrease in density observed at higher temperatures due to thermal expansion. The density of ethanol is also influenced by its concentration, with lower concentrations resulting in lower densities. Understanding the density of ethanol at different temperatures and concentrations is important for a variety of applications, including the production and handling of ethanol-based products.

Besides, ethanol crops offer worrying competition to food crops, which may lead to food price rises. In this section, we describe ways to manage Cookies, including how to disable them.
Density of Solvents as a Function of Temperature
Tables of ethanol density have the same disadvantage as graphs in that they usually include only one set of units. The Cookies are stored by the internet browser. Some of the sophisticated alcohol monitoring systems available today can even measure the water content in ethanol. The calculator does automatic interpolation calculation for density or concentration values that are between those in the table. Ethanol has been used in the last few years as a distillation container or extractive solvent in the chemical industry, as a carrier or additive in food and pharmaceutical processes, and in antimicrobial applications for medical uses.

The most usual methods are alcohol percentage by volume %ABV , alcohol percentage by mass %Mass , molar percentage and alcohol proof. These conversions are frequently required because plant and process design calculations require the strengths to be expressed in mass or molar terms, but for historical reasons most trade is done in volumetric strength terms eg % ABV or proof.

As a result of this, there is a drastic decrease in emissions, which makes it an environment-friendly fuel alternative. Ethanol is derived from grains such as corn and grass varieties such as switch grass. Fortunately we now have computer programs like Tables of ethanol density data achieve high precision at the published combinations of strength and temperature.
