Defining Phase Change

Defining Phase Change is a skill on Pengi from Lesson 4: Freedom of Movement in Amplify Science (California) Grade 7.

Key Concepts

A phase change is fundamentally a shift in freedom. When ice melts, its molecules are not just getting warmer; they are gaining the liberty to break out of their fixed positions.

This transition transforms the substance's observable properties. The shift from a rigid solid to a flowing liquid is the macroscopic result of molecules gaining the freedom of movement to slide past one another.
