Which of the following statements is an exception in the assumptions of the kinetic theory of gases?
- Gases are composed of many elastic particles
- The particles are of negligible size
- The particles are in constant random motion
-
The particles are of negligible mass
- The particles collide with each other
The correct answer is: D
Explanation
The kinetic theory of gases assumes that gas particles are negligible in size:
- Small size: The total volume of the gas particles is negligible compared to the volume of the container.
- Random motion: The particles are in constant, random motion.
- No intermolecular forces: There is no force of attraction between the particles at normal temperatures and pressures.
- Elastic collisions: Collisions between particles are elastic, meaning there is no net loss of energy.
- Kinetic energy: The kinetic energy of the particles is proportional to temperature.
