Everyone will contribute to this page and make it a class review page.  We will start with making sentences.

  1. Select one vocab word and create a sentence here.
  2. Only highlight one vocab per sentence, even if you use multiple vocab in a sentence.

  Kinetic Energy chapter 11
  • Energy related to motion or movement
  • Molecules that more faster have higher KE
  • Temperature = average kinetic energy
   
  Compound chapter 1

substance formed from two or more chemically bonded elements

ex: H2O

  Lewis Dot Structure chapter 3
  • Dots are used to only represent valence electrons
  • valence electrons are electrons found in the outermost/highest energy level of the atom

  Question & Answer Contributor
Q: What is the difference between Kinetic Energy and Potential Energy? Hiep Hua
A:

Energy is the capacity to do work, move, or can be stored.

 

  • PE = Potential Energy is energy that is from structure, position, or organization
  • For example:
    • Sugar molecules lock away energy absorbed from sunlight.
    • Rocks on high hills have PE due to their position.

 

 

  • KE = Kinetic Energy is energy of motion.
  • For example:
    • Molecules can absorb energy and move faster, like warm air/gas when you open an oven.

 

Follow up:

Q:  How does a hot gas compare to a cool gas in terms of energy?

A:  Hot gas has absorbed more energy and therefore moves faster, while cooler gases move slower.
