Question

Please i want the answe to question below.

Use the kinetic molecular theory to explain each of the following.
a) Gases are easier to compress than liquids or solids.
b) Solids have definite shape

Expert Solution

Step 1

The Kinetic molecular theory is used to explain the nature of the substances. The gases can be compressed easily than liquids or solids.

Step 2

a) according to the kinetic molecular theory, in gaseous state the molecules are aligned so far from each other and distance between gas molecules is larger than in solids and liquids so the volume occupied by gas molecules is very less than empty volume, hence gases much more compressible than liquids and solids.

Gases are compressible because most of the volume of gas is composed of the large amount of empty space between the gas particles.

Generally, at room temperature and standard pressure the average distance between gas molecules is about ten times the diameter of the molecules themselves.

But in case of solids and liquids, if we apply pressure, there is essentially no change in volume as there is no space between the individual particles.
