What are the characteristic properties of gas?
The characteristic properties of gases are:
- (a) Gases do not have any definite shape or volume.
- (b) Gases are compressible.
- (c) Gases can be expanded.
- (d) Gases exert pressure in all the directions.
- (e) Gases have low densities.
- (f) Gases diffuse readily.
What is volume in properties of gases?
The volume of a gas is simply the space in which the molecules of the gas are free to move. If we have a mixture of gases, such as air, the various gases will coexist within the same volume. In these respects, gases are very different from liquids and solids, the two condensed states of matter.
Which of the following is are characteristics of gases?
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.
What type of volume is gas?
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. There is a great deal of empty space between particles, which have a lot of kinetic energy.
How are the physical properties of a gas described?
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 is the relationship between volume and volume of gas?
Avagadro’s Law-Gives the relationship between volume and amount of gas in moles when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases.
Why do gasses have no definite volume or shape?
Gasses do not possess any definite volume or shape. They totally fill all the space accessible to them. The characteristic or properties of gases to fill the available volume within a container is the result of the freedom that gas particles have to move everywhere in the accessible space.
How are gases different from liquids and solids?
A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer.
