Asked by Arron?

When performing a scientific investigation on an unknown substance, what is one safe way to test it to determine what it might be?
Answered by DrBob222
Do you have choices for an answer.
If not, here are some suggestions.
Determine its color. Determine its phase (solid, liquid, gas). Determine its density. All of those are physical properties (not chemical properties) but the physical properties will not destroy the integrity of the sample.
