kotegsom [21]

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 \checkmark

  • 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 \checkmark

  • 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 />\times 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 \checkmark

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

PLEASE HELP I HATE CHEM
Orlov [11]
