In kinetic theory of gases, it is assumed that:
A
the collisions are not perfectly elastic.
B
the molecular collisions change the density of the gas.
C
between two collisions the molecules travel with uniform velocity.
D
the molecules don't collide with each other on the wall.
Answer
between two collisions the molecules travel with uniform velocity.
Explanation
Solution
The kinetic theory of gases assumes that gas molecules move randomly in straight lines. Between collisions, there are no significant intermolecular forces or external forces acting on the molecules, so their velocity remains constant (uniform). Collisions are assumed to be perfectly elastic, and molecules do collide with the container walls to exert pressure.
