solubility
of substances, or their ability to be dissolved can be used to identify them.
colloids
are suspensions that aren't easily filtered, because of the small size of the particles.
volume
the amount of space that an object takes up.
volume=length x width x height
matter
anything that has mass and takes up space
liquid
has definite volume but no definite shape.
weight
a measure of the pull of gravity on an object.
combustibility
ability to burn
mass
the amount of matter in an object
solid
has definite shape and volume
texture
how the surface of a substance feels
density
the concentration of matter in an object.
density=mass/volume
physical property
properties that can be observed or measured without changing an object, or any of the materials it's made of, into something else
condensation
changes a substance from a gas to a liquid
ductility
ability of a substance to be pulled into thin threads without breaking
gas
has no definite shape or volume
mixture
combinations of two or more pure substances that are not chemically combined with each other.
evaporation
occurs when particles escape from a nonboiling liquid and become a gas.
solutions
particles of each substance are mixed together evenly
reactivity
ability of a substance to react chemically
stability
steady calm slow to react: A substance with a high stability level is slow to react
reactivity
ability of a substance to go through a chemical change.
suspension
a mixture that contains particles that are large enough to be seen. The particles can be separated from the mixture by lusing filter paper.
buoyancy
ability to float in a liquid or rise in a gas
density
the amount of mass that fits in a given volume.
chemical property
ability of a substance to react with other materials and form new substances
ex. burn coal
combustibility
ability to burn
