give me the ten assumptions of kinectic theory of gases with explanation.
Answers
Gases are made up of molecules. What are molecules? Molecules are the smallest unit which behaves the same as the sample, i.e. they have the same chemical properties as of the sample. The kinetic theory of gases has developed a model which explains the behavior of molecules, which should further explain the behavior of an ideal gas. Do you know what an ideal gas is?
We have learned that the pressure (P), volume (V), and temperature (T) of gases at low temperature follow the equation:
PV = nRT
Where
n = number of moles in the gas
R = gas constant having value 8.314JK−1mol−1
Now, any gas which follows this equation is called ideal gas. But there are certain assumptions that we consider for describing ideal gas behavior.
All gases are made up of molecules which are constantly and persistently moving in random directions.
The separation between the molecules is much greater than the size of molecules.
When a gas sample is kept in a container, the molecules of the sample do not exert any force on the walls of the container during the collision.
The time interval of collision between two molecules, and between a molecule and the wall is considered to be very small.
All the collisions between molecules and even between molecules and wall are considered to be elastic.
All the molecules in a certain gas sample obey Newton’s laws of motion.
If a gas sample is left for a sufficient time, it eventually comes to a steady state. The density of molecules and the distribution of molecules are independent of position, distance and time.

Basic Assumptions Of The Kinetic Theory Of Gases→
●Gas molecules have a constant rapid motion which is randomness that rose from the collisions between the gas molecules.
●Gases have macroscopic properties like temperature, volume, pressure, thermal conductivity are explained by kinetic theory.
