|
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)
|
|
|
density
|
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
(milk sours, digestion, rocket blast, fireworks, buring wood, silver tarnishes, bake a cake, leaves change color in fall. |
|
