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.
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.
Substance
the substance is substance
An element - substance - NOT a mixture.
