The gases in air can be separated from one another through a process known as the fractional distillation of liquid air. This is a process that converts air into a liquid form and then allows it to be portioned out into layers and separated from one another. Because pure oxygen and nitrogen have a number of applications, this is a useful technique.Know More
Fractional distillation is a process that can separate gases from one another if they can be converted into a liquid form. To perform this separation on air, it must be cooled to a very low temperature so that it liquefies. Once this is done, the air can be passed into the bottom of a fractionating column. This column slowly raises the temperature until the oxygen and nitrogen in the air are separate from one another. From there, two tubes separately pipe off the gases.
This process can be repeated on the oxygen because in many cases, there are still trace amounts of argon found in the oxygen. Pure nitrogen, oxygen and argon can be removed from the air by the end of the final fractional distillation. The nitrogen is used in a number of different settings, especially the food and grocery industries.Learn more about Chemistry
Crude oil is separated into fractions by a technique called fractional distillation. This technique separates the hydrocarbons into fractions by heating the crude oil to about 400 degrees Celsius or 752 degrees Fahrenheit.Full Answer >
Crystallization separates a solid dissolved in a liquid that has formed a solution. To crystallize the solid, the solution is heated in an open container to allow the liquid to evaporate, leaving the crystalline solid behind.Full Answer >
Gases and liquids are considered fluids because they both flow and move. The molecules comprising both gases and fluids are constantly in motion in random formations. The molecules continuously collide with each other and the sides of any container in which they are placed.Full Answer >
