Which of the following is NOT a postulate of the Kinetic Molecular Theory? 1. Average Kinetic Energy of the system is a measure of the temperature of the system.
2. Energy is conserved in the collisions between gas molecules..
3. Energy can either be destroyed or created. Its goes from one form to another.
4. Gases travel in straight line until they collide with other gas molecules

"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.

"1. Average Kinetic Energy of the system is a measure of the temperature of the system."

Postulate of Kinetic Molecular Theory

"2. Energy is conserved in the collisions between gas molecules.."

Postulate of Kinetic Molecular Theory

"3. Energy can either be destroyed or created. Its goes from one form to another.

NOT a Postulate of Kinetic Molecular Theory

"4. Gases travel in straight line until they collide with other gas molecules"

Postulate of Kinetic Molecular Theory
