-
volume
the volume of an object is the space it takes up
-
mass
the amount of matter in an object. a balance or scale can measure mass
-
matter
anything that has mass and volume; the building block of everything
-
unit of volume for liquid
mL
-
unit of volume for solid
cc
-
weight
how strong gravity pulls on an object
-
solid form of matter
particles line up in an organized pattern
-
liquid form of matter
the particles move past one another but they remain close together
-
gas form of matter
the particles move very rapidly; they are spread out with a lot of empty space
-
melting point
the temperature at which a solid turns into a liquid
-
vaporization
the change from liquid to gas
-
condensation
gas turning into liquid
-
freezing
the change from liquid to solid
-
evaporation
happens at all temperatures
-
boiling point
happens at one temperature
-
sublimation
the change from a solid to a gas
-
physical properties
do not change the matter but can change its appearance; color, smell, freezing point, boiling point; dissolving sugar in water, cutting grass, ripping shirt, trail mix
-
chemical properties
only seen during a chemical reaction; heat of combustion, burning wood, fireworks, changing leaf colors, digestion food;
-
heat
the transfer of thermal energy from one piece of matter to another
-
condensation
the transfer of thermal energy by particles of matter bumping into each other
-
insulators
materials that don't conduct thermal energy well; styrofoam, rubber, wood
-
convection
a large group of hot particles can move and transfer thermal energy
-
conductors
materials that conduct thermal energy well; most metals, water, glass
