It is a state of matter that is molded into the shape of a container in which it is found.
It adopts a density similar to that of the container, even if there is gravity.
If the gaseous substance, also called vapor, is not in a container, it will spread out into space.
The word gas is attributed to the state or situation presented by the matter that possesses this state.
- Oxygen is kept at a room temperature of approximately 20 ° C or 68 ° F.
- The hydrogen temperature is ambient and the water has an atmospheric pressure with a temperature greater than 100 °.
- When a substance in the gaseous phase is heated , the atoms and particles reach kinetic energy and are agitated rapidly.
- When it happens that a substance of gaseous matter is cooled, the atoms or particles release kinetic energy and are slowly agitated.
- If the temperature becomes high, a variety of gases, such as hydrogen, will quickly adjust to other gases such as chlorine or oxygen.
- Gases do not have a definite volume or shape.
- The common paths of the atoms are appropriately large so that the interactions between the atoms are independent of their inclination.
- Gases contract and diffuse in predictable amounts due to changes in temperature and pressure.
- The pressure of a gas is transformed due to the increase of a gas confined to the volume of the container in which it is found, as well as the appropriate pressure and temperature.
- The volume of a gas is similar to the volume of a container.
