Which of the following statements about the kinetic theory of gases is NOT true:
|
All molecules move with the same speed.
|
|
Their average kinetic energy is directly proportional to the absolute temperature.
|
|
All molecules make elastic collisions with each other and the walls of the container.
|
|
The molecules travel in straight lines until they collide.
|
Explanation:
Detailed explanation-1: -The correct answer is option 3) i.e. Kinetic energy of molecules changes when they collide with the wall of the container. CONCEPT: Kinetic theory of gas: The kinetic theory of gases assumes that: The molecules of a gas are constantly moving.
Detailed explanation-2: -Pressure does not have any effect on the kinetic energy of the molecule.
