Answer Question in box below Q: What is your evidence for why you think a Fan not spinning has energy or does not have energy-explain in detail?

Yes,  a fan not spinning has energy

Explanation:

Let us remember that energy is neither created nor destroyed but is transformed from one form to another. This is known as the principle of energy conservation. Hence energy in the universe never disappears!

The fan that is not spinning has potential energy. Potential energy is energy possessed by a body by virtue of its position. When the fan starts spinning, this potential energy is converted to kinetic energy.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
