A student must prepare a poster display that describes
three criteria that must be met for a sample of a liquid to
change state to a solid. What are the criteria?

These are the three criteria that must be met:

In other words, heat must be eliminated from a sample to freeze it for the kinetic energy to be removed. This means the sample must be cooled down.

The particles are in clusters, but as more energy is eliminated by cooling, the particles begin to align themselves,thus forming a solid. This is called freezing. The temperature at which the freezing occurs is known as the freezing point of the sample. So during freezing, a liquid gets converted into a solid.
