Kerosene is widely used to power jet engines of aircraft , as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. [2]
Cooking oil (also known as edible oil) is a plant or animal liquid fat used in frying, baking, and other types of cooking. Oil allows higher cooking temperatures than water, making cooking faster and more flavorful, while likewise distributing heat, reducing burning and uneven cooking. It sometimes imparts its own flavor.
An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils). Oils are usually flammable and surface active .
Its chemical formula, H 2 O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. [21] In liquid form, H 2 O is also called "water" at standard temperature and pressure.
The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions .
Most triglycerides are unsymmetrical, being derived from mixtures of fatty acids. Triolein represents 4–30% of olive oil. [1] Triolein is also known as glyceryl trioleate and is one of the two components of Lorenzo's oil. [2] The oxidation of triolein is according to the formula: C 57 H 104 O 6 + 80 O 2 → 57 CO 2 + 52 H 2 O
In addition to the microscopic kinetic energies of its molecules, the internal energy of a body includes chemical energy belonging to distinct molecules, and the global joint potential energy involved in the interactions between molecules and suchlike. [6] Thermal energy may be viewed as contributing to internal energy or to enthalpy.
It is an odorless, colorless oil, although commercial samples may be yellowish due to the presence of impurities. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9, and a main product of Δ9-desaturase. [2] It has the formula CH 3 −(CH 2) 7 −CH=CH−(CH 2) 7 ...
