properties of gases
Answers
➡️Intermolecular space is the least in gases.
➡️They are free to move.
➡️They have no definite shape or. volume.
➡️Gases are highly compressible.
➡️Have very low density.
➡️The rate of diffusion is very high.
➡️Fluidity is the most compared to solids and liquids.
➡️The particles are highly energetic.
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
Examples of Gases
Air.
Helium.
Nitrogen.
Freon.
Carbon dioxide.
Water vapor.
Hydrogen.
Natural gas.
Gas particles spread out to fill a container evenly, unlike solids and liquids. Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal combustion engine provides a good example of the ease with which gases can be compressed.
Characteristics of Gases
Gases have neither definite shape nor definite volume. They expand to the size of their container.
Gases are fluid, and flow easily.
Gases have low density, unless compressed. ...
Gases diffuse (mix and spread out) and effuse (travel through small holes).
In a solid, molecules are packed together, and it keeps its shape. Liquids take the shape of the container. Gases spread out to fill the container. Solid is one of the three main states of matter, along with liquid and gas
Because most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature
What Are Five Properties of Gases?
Low Density. Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states. ...
Indefinite Shape or Volume. ...
Compressibility and Expandability. ...
Diffusivity. ...
Pressure.
Elemental Gases
Hydrogen (H)
Nitrogen (N)
Oxygen (O)
Fluorine (F)
Chlorine (Cl)
Helium (He)
Neon (Ne)
Argon (Ar)
Carbon dioxide, in all kinds of fizzy beverages, and in fire extinguishers. Nitrogen, in cans of Guinness stout (to give it that distinctive head) and in fire suppression systems. Propane & Natural Gas used in gas burners and as an automotive fuel. Butane is used in cigarette lighters and gas camping stoves.
Fire is an oxidizing chemical reaction that releases heat and light. The actual flames that you see moving and glowing when something is burning are simply gas that is still reacting and giving off light. Plasmas are gases in which a good fraction of the molecules are ionized.
