What theory explains that particles are in constant random motion or vibration?

A. Kinetic molecular theory
B. Potential molecular theory
C. Microscopic molecular theory
D. Macroscopic molecular theory


Sagot :

Final answer:

The kinetic-molecular theory explains that gas particles are in constant random motion or vibration due to their rapid, random motion and elastic collisions, influenced by temperature.


Explanation:

The kinetic-molecular theory explains that particles are in constant random motion or vibration. This theory states that gas particles are in constant rapid motion in random directions, colliding elastically with each other and the container walls. The average kinetic energy of gas particles is dependent on the temperature of the gas.
