Any teacher here?
Pls explain me the kinetic theory of matter 3rd assumption in the above image with examples ( if it is necessary )

Answer:
By the late 19th century, scientists had begun accepting the atomic theory of matter started relating it to individual molecules. The Kinetic Molecular Theory of Gases comes from observations that scientists made about gases to explain their macroscopic properties. The following are the basic assumptions of the Kinetic Molecular Theory:
The volume occupied by the individual particles of a gas is negligible compared to the volume of the gas itself.
The particles of an ideal gas exert no attractive forces on each other or on their surroundings.
Gas particles are in a constant state of random motion and move in straight lines until they collide with another body.
The collisions exhibited by gas particles are completely elastic; when two molecules collide, total kinetic energy is conserved.
The average kinetic energy of gas molecules is directly proportional to absolute temperature only; this implies that all molecular motion ceases if the temperature is reduced to absolute zero.

These simplifying assumptions bring the characteristics of gases within the range of mathematical treatment.Such a model describes a perfect gas and is a reasonable approximation to a real gas, particularly in the limit of extreme dilution and high temperature. Such a simplified description, however, is not sufficiently precise to account for the behaviour of gases at high densities
Answer:
The following are the assumptions made regarding the motion of molecules in matter:
1. Molecules are in a state of continuous motion and possess kinetic energy.
2. The kinetic energy of molecules increases with an increase in temperature and decreases with a decreases in temperature.
3. The molecules of matter always attract each other due to the intermolecular force of attraction.
4. Molecules of matter have space in between them.
5. If the intermolecular space is small, intermolecular force of attraction increases.
