AQUATICS |
|
The term aquatic refers to water and can be either a noun or an adjective. Dictionary definitions do not specify what kind of water, although in both general use and in the sciences, the implication is that of fresh water. The term marine is typically substituted where reference to salt water is intended.

Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue. Broadly speaking, fuel oil is any liquid petroleum product that is burned in a furnace for the generation of heat or used in an engine for the generation of power, except oils having a flash point of approximately 40 °C (about 100 °F) and oils burned in cotton or wool-wick burners. In this sense, diesel is a type of fuel oil. Fuel oil is made of long hydrocarbon chains, particularly alkanes, cycloalkanes and aromatics. Factually and in a stricter sense, the term fuel oil is used to indicate the heaviest commercial fuel that can be obtained from crude oil, heavier than gasoline and naphtha.
