Gasses

Do you know?

A gas is a substance that is in a gaseous, or vaporous state of ​matter. The term gas is also used in reference to the state itself ​when applied to matter that has the properties of a gaseous ​substance. Gas is one of the three natural states of matter, along ​with solid, and liquid. A gas has no fixed shape nor volume. Gasses ​expand to fill the container while decreasing density until evenly ​spread out, as gasses take the shape of their container, the space ​between particles in a gas is large. Also, it is a state of matter that is ​active in terms of molecule/atom movement.

CHARACTERISTICS OF ​GASSES:

• gasses have neither definite shape nor definite volume. They expand ​to the size of their container.
  
• gasses are fluid, and flow easily.
  
• gasses have low density, unless compressed. Being made of tiny ​particles in a large, open space, gasses are very compressible.
  
• gasses diffuse (mix and spread out) and effuse (travel through small ​holes).
