what are the two properties of matter?

Question

are they volume and mass?

Answer 1

Yes.

Some people would say "inertia" rather than "mass" since it seems more descriptive, but that is a mere technicality.

Answer 2

al properties of matter are categorized as either Intensive or Extensive:

o Intensive - Properties that do not depend on the amount of the matter present.
+ Color
+ Odor
+ Luster - How shiny a substance is.
+ Malleability - The ability of a substance to be beaten into thin sheets.
+ Ductility - The ability of a substance to be drawn into thin wires.
+ Conductivity - The ability of a substance to allow the flow of energy or electricity.
+ Hardness - How easily a substance can be scratched.
+ Melting/Freezing Point - The temperature at which the solid and liquid phases of a substance are in equilibrium at atmospheric pressure.
+ Boiling Point - The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure).
+ Density - The mass of a substance divided by its volume

o Extensive - Properties that do depend on the amount of matter present.
+ Mass - A measurement of the amount of matter in a object (grams).
+ Weight - A measurement of the gravitational force of attraction of the earth acting on an object.
+ Volume - A measurement of the amount of space a substance occupies.
+ Length

Answer 3

Definition of matter.=Any material substance in order to exist must have a volume whether its a Mass structure or a Space structure.

Mass less photons as per the standard model of Physics,exist because they are believed to be to have zero mass and zero volume. Yet it is believed to have momentum. This scenario just does not fit the above definiton of Matter.

Therefore it is just a question of beliefs in Science. As the old saying goes="Believe it or not"

Answer 4

Simply, yes. Matter has mass and takes up space.
