Examples of aggregation states

What does the word aggregation mean ? For some, it means incorporating something into someone or something. For others, expand or add. All are correct. But when you talk about states of aggregation you think of an element that is transformed.

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

  1. Water, acetone, milk, fruit juices, oil, glycerin, vinegar, petroleum.
  2. 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

  1. Table salt, pearls, refined sugar, gypsum, coal, sulfur, wood, sand.
  2. 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

  1. Sky clouds, helium, methane gas, inflatable gas balloons, tear gas.
  2. Carbon monoxide, butane, water vapor, dioxygen, dichlor, krypton.
