Examples of Liquids

We explain that what are examples of liquids? The liquids are all substances that are in liquid state , one of the states of aggregation of matter. They are characterized by the fact that their molecules are further apart than in solids, but much closer together than in liquids. In reality, all substances can appear in a liquid state, they will only depend on temperature and pressure for this to be achieved. A metal like iron can be a liquid if it is heated to thousands of degrees Celsius. what are examples of liquids

However, by convention, when we speak of liquids we are going to refer to the elements and compounds that manifest themselves in this way under normal conditions of temperature and pressure (NTP: 20 ° C, 1 atm) . In other words, in our environmental conditions. These are the cases of water (H 2 O), mercury (Hg), bromine (Br 2 ), sulfuric acid (H 2 SO 4 ), hexane (C 6 H 14 ), ethyl alcohol (C 2 H 5 OH), among other substances of various chemical natures.

Properties of liquids

Liquids have properties that undoubtedly distinguish them from solids and gases. These have to do, above all, with their behavior in space. First, they do not have a geometric shape , rather they acquire it by being contained in a container. They are organized according to gravity and atmospheric pressure; the container walls only delimit the place they encompass. When in motion, the molecules are moving layered or lamellar clusters.

Liquids tend to flow , that is, to go to a place where it can be at rest or less exposed to conditions that cause it to move. A liquid flows when it is on an inclined surface : by action of gravity, it will go to the lowest part, until it stops. Also when they find a space available in the container, such as a hole in the bottom, the liquids escape driven by their own weight, until they reach the level of the hole. what are examples of liquids

Liquids have a property called viscosity , which is their resistance to flow. There are liquids such as honey that, even if they are tilted up to 90 °, will remain fixed or will begin a slow movement. Honey is one of the most viscous substances. Now, if we talk about ethyl alcohol , we will see in it a very low viscosity. It is so easy to move that sometimes the surface has to be moved in a controlled way so that it does not overflow or splash. what are examples of liquids

Liquids have very varied densities . The diversity of known liquids makes it difficult to establish a range. Depending on the liquid in question, it will be the volume that each unit of its mass covers. The water is one of the liquid denser , having a value of approximately 1 g / mL at NTP conditions. The oils, made up of unsaturated fatty acids, have a lower density than that, so when they are put together in a glass, the water remains at the bottom.

Liquids also have capillarity , which is the property that makes them go through the pores of a surface and reach its most internal parts. Capillarity occurs in sponges, wood, and porous minerals. It is also used in mercury thermometers. These temperature gauges have a bulb filled with mercury at the bottom, a metal that expands in contact with heat. And above the bulb there is a capillary tube through which it will ascend.

Liquids are capable of changing to other states, solid and gaseous, in response to the temperature at which they are. Here are two of its most important properties: the boiling point and the freezing point . The boiling point is the temperature at which the liquid begins to boil, gradually turning into vapor and, at a higher temperature, into gas. The freezing point is the temperature low enough for it to become a solid.
