What is Fractional Distillation?

Fractional distillation is the separation of various components from a liquid homogeneous mixture. Each component typically has a different boiling point and vapour pressure than the rest, so fractional distillation can be achieved by applying a temperature gradient. The various components are condensed at different stages or levels of the setup, which can either be a small setup consisting of...

What is the Distillation Process?

Distillation is the process of purifying a substance, whereby pure substances are extracted from a mixture.  There are different types of distillation processes, including fractional distillation, simple, steam, and vacuum distillation. Distillation has several commercial and industrial applications. For example, it can be used to distil wine. In fact, the well-documented use of distillation can be traced as far back as...

What is Viscosity in Chemistry?

Viscosity is the tendency of fluids, in either liquid or gas form, to resist forces that act against them. For example, if you tried to rapidly stir pure water while rapidly stirring molasses, you would find it much more difficult to stir the latter. With this in mind, viscosity can also refer to how thick a fluid is. Viscosity can...

What is the Definition of Evaporation in Chemistry?

Evaporation is a natural or synthesised process by which liquid substances transition into a gaseous state with the action of heat.  The water cycle, which involves the evaporation and precipitation of water, is one of the major driving forces of the weather and global climate, and one of the best examples of evaporation. Evaporation is generally a cooling process that has...
