Fractional distillation is a high-temperature process that separates liquids and gases from unrefined crude oil. According to experts at How Stuff Works, there is a variety of elements in crude oil that are of different ... More »

The fractional distillation of air is a process by which the substances in air are separated, evaporated and measured as they condense at different temperatures. Fractionally distilling air in this way makes it easier to... More »

Food producers use distillation as a way to purify water by boiling it, then collecting the steam and cooling it so it condenses into a purified product. Oil refineries use fractional distillation to separate petroleum i... More »

Fractional distillation involves boiling crude oil so that the various types of hydrocarbon molecules present vaporize, each in turn. The vapors are then condensed into separate batches according to type. More »

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 ... More »

Solids, liquids and gases are the three main phases of matter. Solids have a fixed crystalline structure, whereas liquids and gases are more free-flowing. The phase of matter that a given substance exhibits depends on te... More »

The primary difference between liquids and gases is that the constituent molecules of liquids are closer together and move less than those that make up gases. Liquids and gases behave in a number of similar ways, althoug... More »
