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

What is the volume of the granite piece in cubic centimeters
Ghella [55]
Hi there!

Your correct answer will be 12.2 cm³.

This is how you get there:

1 mL = 1 cm³

With this one conversion factor, you can extrapolate the final answer. When you add the granite to the water, which is filled to 25.0 mL, the water level then moves to 37.2 mL. If you subtract the before volume from the volume after, you will get an answer of 12.2 mL. Then use the conversion factor and, voila! 12.2 cm³

I hope this helps!
