Question

What are the four postulates of kinetic molecular theory

Answer 1

postulates of kinetic molecular theory are :

1. atom of any substance are very, very small.

2. atoms of the substance attract each other and this force is called inter molecular force.

3,particles of substances have space between them and this space is called inter molecul space.

4. particles of substances are constantly moving in zig-zag direction.

Answer 2

$\huge\mathcal\blue{Answer:}$

$\boxed{\red{\texttt{Kinetic\:molecular\:theory\:of\:gases}}}$

1)Gases contain large number of tiny and discrete particles called molecules

2)Gas molecules are very much apart from each other

3)The molecules move randomly in all directions with high velocities

4)The collisions between gas molecules of perfectly elastic

5)pressure exerted by a gas is due to collisions of molecules made on the walls of the vessel

6)KE is directly proportional to the temperature

7)Molecules are electrically Netural and do not have attractions or repulsions between them

8)Molecular motions are unaffected by gravity
