Question

Which of the following is NOT a postulate of the Kinetic Molecular Theory?

Answer 1

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.

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

Postulate of Kinetic Molecular Theory $\checkmark$

• The average kinetic energy of the system is measured by its temperature and nothing else

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

Postulate of Kinetic Molecular Theory $\checkmark$

• All collisions between gas molecules are perfectly elastic, meaning no energy is lost

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

$\times$ NOT a Postulate of Kinetic Molecular Theory

• Related to Conservation of Energy from thermodynamics

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

Postulate of Kinetic Molecular Theory $\checkmark$

• All gas molecules will travel in a straight line until they collide with other gas molecules or some object (e.g. a container)
