What will happen to Blake’s substance if he transfers energy out of the substance and causes a phase change?

Back

The substance’s molecules will move slower and be a solid.

How are Substance 1 and Substance 2 different when only Substance 1 changes phase after removing the same amount of kinetic energy?

Back

Substance 1 has a stronger attraction between its molecules than substance 2. Its molecules now move in place.
