A company uses a substance that is Solid under normal conditions this substance will be used in extreme conditions which could make this substance molecules move faster and cause a phase change how would this phase change occur , and how would the molecules of the substance be affected under these extreme conditions

Extreme heat will cause the substance molecules to move faster and cause a phase change this phase change would occur if left in an extremely hot area causing the molecules to spread apart.

that's it!
