Same Molecules, Different States
Same Molecules, Different States is a skill on Pengi from Lesson 3: Molecular Scale (Gases) in Amplify Science (California) Grade 7.
Key Concepts
A phase change alters the form of a substance, not its identity. Water ice, liquid water, and water vapor are all made of the exact same molecules .
The molecule itself never changes; it does not melt or expand. Instead, the arrangement and movement of the molecules change. Determining the state of matter is about observing how the molecules interact, not what they are made of.
