TermDefinition
matter anything that has mass and volume
property characteristic

hardness the quality of being hard (int. and physical)
state whether it's a solid (s), liquid (l), or gas (g) (int. physical)
color The pigment it is (int. physical)
malleability if you can bend it; it flexibility (int. physical)
density m/v its a # but its intensive and physical
temperature it's a # but it's intensive and physical
extensive affected by the amount of the substance
volume ext and physical m/d
mass it's weight w/o gravity affecting it (ext physical)
perimeter it's surrounding (ext physical)
circumference area of a circle (ext physical)
physical properties can be observed and measured w/o changing the composition (chem formula) of matter, can be intensive or extensive
