The liquid is the substance that is shown in that state, taking into account that there are also the solid and the gaseous. It differs from them in that it is very fluid, since the degree of cohesion of the molecules is quite fragile and the number of particles is quite large, so that shocks and friction between the different particles are common.
It is a substance that is not capable of filling the entire space in which it is poured, as is the case with gas, but it has the ability to tenaciously maintain its viscosity , not counting the application of cold or heat. What it does offer is being able to take the shape of the container in which it is made but without being compressed, since the molecules are very close together.
Liquid encompasses chemical elements, liquid metals such as gallium or mercury, and mixtures and compositions of solids that have been fractionated so much that they act as if they were a liquid.
Water is a substance that is made up of one oxygen atom and two hydrogen atoms (H 2 O). Normally it refers to the liquid state but sometimes it can be found in a solid (ice) or gaseous (vapor) form.
Glycerin refers to an organic compound found in vegetable oil and animal fat, being a clear liquid, odorless at room temperature and with a sweet taste. It is normally used to produce soap or as a significant component in pharmaceuticals.
Milk is a whitish, liquid substance produced by the mammary glands of female mammals in order to nourish creatures and preserve their gastrointestinal tract from reasons such as toxins or pathogens.
Formaldehyde is obtained by purification of methyl alcohol, which at normal degrees is a gas but solutions diluted to 40% cause it to become formaldehyde . That is a liquid without color and with a strong and overwhelming smell.
Phosphoric acid is a chemical substance that, if present at 20ºC and with a concentration of 50-70%, is a mobile translucent liquid and if it is at 80%, it is a colorless glutinous liquid or with a yellow touch. It is used as a conditioning substance for the upper part of the oral enamel or as a component of some non-alcoholic beverages, such as soft drinks.
Petroleum is a combination of organic elements, primarily fuel, indissoluble in water. It is a natural oily and flammable liquid found in nature, for example in marine or continental geological beds.
The oil is called the fatty liquids that have vegetable, animal or mineral roots , it is also an insoluble substance in water, flammable and that is formed by esters of fatty acids or hydrocarbons originating from petroleum.
Mercury or formerly called liquid silver, is the only chemical element that is liquid under normal laboratory circumstances , except bromine. It is used in thermometers, barometers, vacuum pumps or fluorescent lamps, among others.
