Answer:
"3. Energy can either be destroyed or created. Its goes from one form to another."
Explanation:
The third answer choice, "3. Energy can either be destroyed or created. Its goes from one form to another. " is related to the Law of Conservation of Energy from thermodynamics. Is it not a postulate of the Kinetic Molecular Theory.
<u>"1. Average Kinetic Energy of the system is a measure of the temperature of the system."</u>
Postulate of Kinetic Molecular Theory
- The average kinetic energy of the system is measured by its temperature and nothing else
<u>"2. Energy is conserved in the collisions between gas molecules.."</u>
Postulate of Kinetic Molecular Theory
- All collisions between gas molecules are perfectly elastic, meaning no energy is lost
<u>"3. Energy can either be destroyed or created. Its goes from one form to another.</u>
<u /> NOT a Postulate of Kinetic Molecular Theory
- Related to Conservation of Energy from thermodynamics
<u>"4. Gases travel in straight line until they collide with other gas molecules"</u>
Postulate of Kinetic Molecular Theory
- All gas molecules will travel in a straight line until they collide with other gas molecules or some object (e.g. a container)
