which state of matter is highly compressible, is made of particles moving independently of each other, and is present in large quantities near
earth's surface?
a
solid
b. liquid
c. gas
d. plasma

gaseous

Explanation: It is also known that Earth's atmosphere is surrounded by various gases. Thus, we can conclude that gaseous state of matter is highly compressible, is made of particles moving independently of each other, and is present in large quantities near Earth's surface.

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.

d.) circle motion requires a force to give it a centripetal acceleration.
