Is Flammability a Chemical or Physical Property? Flammability is a chemical property. It involves chemical change. To determine whether a material is flammable, you test the material by applying heat. If it burns, the material undergoes a chemical reaction, demonstrating its flammability. Flammability...
CHEMICAL PROPERTIES Chemical properties can ONLY be observed AS the substances are changing into different substances. Chemical changes, or chemical reactions, are changes that result in the production of another substance. FLAMMABILITY: A material’s ability to BURN in the presence of OXYGEN REACTIVITY...

Limitations:Many minerals come in multiple colors, and environmental conditions or chemical impurities can alter the color, making it an inconsistent property for identification on its own. Transparency Transparency refers to how much light passes through a mineral. It is a measure of the mineral’s...
