Density as a Key Property
Density as a Key Property is a skill on Pengi from Lesson 1: Observing Properties in Amplify Science (California) Grade 7.
Key Concepts
Some properties, like mass or volume, can change depending on how much material you have. However, density —the amount of matter in a specific space—never changes for a pure substance.
Because density is an intrinsic property , it serves as a reliable "fingerprint" for identification. Calculating the density of the reddish coating proves it is mathematically distinct from the iron pipe it covers.
