The ability for it to burn (combust).
it is not flammable
no
Yes!
Oxygen is not flammable
It is non-flammable.
No, that is a chemical property.
Flammibility
Calcium is best described as combustible rather than flammable. It will burn, but you have to work at it.
Substance
the substance is substance
An element - substance - NOT a mixture.
physical properties are properties that can ONLY ne observed by changing the chemical identidy of the substance. example: ph,flammibility, wether it dissolves or not,how it reacts to water... physical properties are properties that can be observed without having to change the substance. example: smoothness, wetness, its color ,its smell ,its texture...hope it helped ----------------------------------------------- Physical properties: density, color, hardness, electrical conductivity, thermal conductivity, viscosity, tensile strength, malleability, magnetic properties, refractive index, etc. Chemical properties: reactivity, solubility, aptitude to thermal degradation, toxicologic properties, valences, heat of combustion, enthapy of formation, flammability, bonding type, oxydation reactions, etc.
