Kinetic Energy Challenges Molecular Attraction
Kinetic Energy Challenges Molecular Attraction is a skill on Pengi from Lesson 2: The Competition in Amplify Science (California) Grade 7.
Key Concepts
Molecules in a substance are in a constant tug of war. The kinetic energy of the molecules makes them move and spread apart. At the same time, a constant force of molecular attraction pulls the molecules back together.
This "competition" between movement and attraction determines if a substance will change phase. A phase change happens only when the molecules' movement becomes strong enough to overcome the attraction. If the attraction is still stronger, the substance remains in its current phase.
