Final Jeopardy
Class-ification
Of Matter
This property describes how much mass is In a given volume of material.
BackANSWER: What is density?
Density does this when the mass of an object stays the same, but the volume increases.
BackANSWER: What is decrease?
Any of these types of changes….bubbles, changes color, forms a precipitate,
it burns, temperature change without heating/cooling.
