6 characteristics of the GASEOUS state and examples
The characteristics of the gaseous state are that they have no shape or volume, that they have little density, that the particles move chaotically, that they can be compressed... We tell you in a Teacher!
Matter can be found in different forms in nature, According to their state of aggregation, they are classified as a gaseous state, a liquid state, and a solid state. This classification is due to the organization of the particles that compose it and this depends on the kinetic energy and the distance between the particles. In this lesson from a Teacher we will discover what are the characteristics of the gaseous state of matter.
He gaseous state is one of the three physical states of matter, with him solid state and the liquid state. The states in which we find matter vary according to how are particles found that form a substance, how is their organization and distribution in space and how they behave in certain conditions of pressure and temperature.
In the gaseous state, the particles tend to be far apart from each other and exhibit a lot of motion,
moving in all directions, they translate, rotate and vibrate. Due to this behavior, they do not have a defined shape or volume of their own, which is why they tend to occupy the entire container that contains them. Like the liquid state, it has the ability to flow.The transition from one state to another, as from liquid to gas, is produced by a pressure and temperature variation. High temperature and low pressure are typical conditions for the gaseous state, although this can vary depending on the substance.
Not all materials can exist in a gaseous state at normal temperatures and pressures. Some substances need to be brought to extremes of temperature and pressure in order to be transformed into gases, while the nature of other materials exist at temperatures and normal pressures.
The properties of gases include their ability to expand occupying all available space, low density compared to liquid or solid substances. They can be compressed, since there is a lot of space between their particles. They have the ability to spread and mix quickly, and are light in weight.
