Question

which of the following happen during this change of state? select all that apply. the particles in the substance move far apart. the particles in the substance break down and change into other particles.

Explanation:

In a solid - to - liquid phase change (melting), the particles gain energy. They break the fixed positions they had in the solid state and start moving more freely. The intermolecular forces weaken, allowing the particles to move further apart from their fixed lattice positions in the solid. However, the particles do not break down into other particles as this is a physical change not a chemical change.

Answer:

The particles in the substance move far apart.
