Physical matter, of course. :)
Saying this cause I just took a bio test. Good luck. x
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
physicalNo. It's a physical property
Substances have many different traits, which include such things as phase (solid, liquid, or gas), density, hardness, color, reactivity, flexibility, scarcity or abundance, toxicity, etc.
You observe their properties. A property describes an object, for example the property of a rock is hardness, a property of a person is eye color. Properties can also describe how an object behaves.
The hardness of bone is due to the calcium salts deposited in it.The exceptional hardness of bone, which allows it to resist compression, is attributed to the presence of inorganic hydroxyapatites. Hydroxyapatites such as calcium phosphates are particularly important for bone hardness. Organic substances such as collagen fibers contribute to tensile strength, but not to hardness.the presence of inorganic hydroxyapatites.
physical property
Examples: chemical reactivity, toxicity, flammability, stability.
hardness ductility malleability
No. Physical properties are things like boiling point and hardness; Chemical properties have to do with outer electron shells and how they're shared with other elements.
The physical properties are hardness, cleavage, color, and luster.Halite does not have any chemical properties.
A rock's property's include the color, hardness, luster, and chemical composition.
Hardness and density are physical properties, not changes.
Physical properties: density, melting point, boiling point, hardness, refractive index, resistivity etc.Chemical properties: chemical reactivity, electronegativity, flammability, corrosivity, heat of combustion etc.
hardness, luster, cleavage and fracture, color (not quite useful) and streak
Some physical properties are: density, color, refractive index, hardness, thermal conductivity, electrical conductivity, melting point, boiling point etc. Some chemical properties are: reactivity, corrosiveness, inflammability etc.
Hardness and melting point are physical properties.
color, hardness, chemical composition, system of crystallization, refractive index, luster, magnetic properties, radioactivity, fracture characteristics, etc.
