The Energy Threshold
The Energy Threshold is a skill on Pengi from Lesson 3: Explaining the Delay in Amplify Science (California) Grade 7.
Key Concepts
Phase changes are not instant. Because molecular attraction is always pulling, molecules need a specific amount of energy to break free.
They must build up enough kinetic energy to reach a "tipping point." Until this threshold is crossed, the attraction holds strong, and the substance remains in its current phase.
