weight vs mass
weight can change depending on gravity, but mass stays the same anywhere in the universe (unless you remove some of the matter)

amount of matter in a given amount of spave (mass/volume); density of water is 1 g/ml
float
less dense then water
sink
more dense then water
physical property
a property that does not change the matter's identity

(color, size, shape, texture, conductivity, magnetism, solubility(disolve), state of matter, density, ductile, malleable (bendable), boling or melting point, specific heat
physical change
change that does not form a new substance; matter always retains its identity

(melting ice, tearing paper, crushing a can, painting a bike, dissolving sugar)
chemical properties
describes matter on its ability to change into a new substance
(flammability, reactivity
chemical change
change in which a NEW SUBSTANCE is formed
