What are the seven postulates of Kinetic Molecular Theory?


​

Answer 1

Postulates of Kinetic Theory

1. Gas particles are in constant, rapid motion and move in straight lines.

2. Gas particles are very small in comparison to the distances between them.

3. Gas particles exhibit very little attraction towards each other because they are so far apart.

4. Gas particles collide with each other in a manner which conserves energy.

5. The kinetic energy of the gas particles can be measured by temperature.

Note:- 6 and 7 is not confirmed !

Hope it helps...:)

✨ postulates✨

• Each gas is made up of a large number of small (tiny) particles known as molecules.
• The volume of a molecule is so small that it may be neglected in comparison to total volume of gas.
• The molecules are never in stationary state but they are believed to be in chaotic (random) motion. They travel in straight line in all possible directions with altogether different but constant velocities. The direction of motion is changed by the collision with container or with the other molecules.
• The collision between molecules is perfectly elastic i.e., there is no change in the energies of the molecules after collision.
• The effect of gravity on molecular motion is negligible.
• The kinetic energy of the gases depends on the temperature.
• The pressure of the gas arises due to collision of molecules with the walls of the container.
