For example, a liquid can transform into a solid state like ice. But, it can also become a gaseous state when it emanates gases when boiled . There are three states of aggregation: liquid, solid and gaseous .
There is also a fourth state of aggregation: plasmatic . This state can only be appreciated through extremely high temperatures. The plasma state is observed in ionized atoms.
The liquid , solid and gaseous states of aggregation are the best known . The most popular example is water. When it is subjected to high temperatures, it transforms into a solid or gaseous state. In the same way, the states of aggregation are also reversed according to the temperature to which they subject matter .
What are the aggregation state changes?
- Solidification . A liquid can be subjected to low temperatures until it becomes a solid.
- Merger . A solid is subjected to high temperatures and turns into a liquid.
- Vaporization . A liquid is transformed into a gaseous one by high temperatures.
- Condensing . The temperature of the gaseous state is lowered until reaching the liquid state.
- Sublimation . The solid state becomes a gaseous state by violent increase in temperature and pressure itself.
- Reverse sublimation . The gaseous state becomes solid when the temperature is violently decreased.
Properties of the liquid state of aggregation
- Because of its surface tension . The strong attraction of particles in all directions in the liquid state.
- Because of its viscosity . Opposing force in a fluid when it moves at different pressure (manifests itself when the liquid is in motion).
- Because of its capillarity . Ease of liquids to rise to a small diameter tube (called “capillaries”). In this case, the cohesion force is exceeded by the adhesion force.
- For its fluidity . Ability of a liquid to pass through a hole that is at the same level of the container where it is.
Examples of liquids
- Water, acetone, milk, fruit juices, oil, glycerin, vinegar, petroleum.
- Saliva, benzene, chloroform, chlorine, acetic acid, phosphoric acid.
Properties of the solid state of aggregation
- Because of its elasticity . They deform and do not regain their original shape.
- Because of its shape and volume . Some solids can be enlarged and reduced. They also increase in volume when heated and decrease when cooled.
- For being crystalline and for being amorphous . The first is referred to by its regular atomic structure. The second, by the irregularly arranged particles.
Examples of solids
- Table salt, pearls, refined sugar, gypsum, coal, sulfur, wood, sand.
- Plastic, granite, earthenware, marble, stone, ceramic, quartz, diamond.
Properties of the gas aggregation state
- For being fast and uncontrolled . It can take the shape and place that it contains in a container.
- Because of its small density . Its density is smaller than liquid and solid. That is why the gas is more noticeable.
Examples of gases
- Sky clouds, helium, methane gas, inflatable gas balloons, tear gas.
- Carbon monoxide, butane, water vapor, dioxygen, dichlor, krypton.
