Hello!

The scientific study of the behavior of matter near 0K is called cryogenics

The word "cryogenics" comes from the greek kyros (cold) and geneia (generation). It describes the techniques used to reach very low temperatures to study the behavior of matter.

The ways to achieve these low temperatures are various, but here are the most common:

Have a nice day!

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.
