Matter
Property
Thermal Energy
Anything that has mass and takes up
space.
Describes matter: color, shape,
luster, etc.
Heat energy: causes change in
states of matter.
Properties of Water
Melting Point
Temperature at which ice becomes a
liquid.
Boiling Point
Temperature at which liquid water
becomes a gas.
Freezing Point
Temperature at which liquid water
becomes a solid.
Measuring Matter
Temperature
How hot or cold something is.
Changing States of Matter
Mass
Amount of matter in an object.
Measured with a balance.
Melting
Change in state from solid to liquid.
Freezing
Change if state from liquid to solid.
Condensation
Change in state from gas to liquid.
Evaporation
Change in state from liquid to gas.
Volume
How much space matter takes up.
States of Matter
Solid
State of matter with a definite shape
and volume.
Liquid
State of matter with a definite
volume but NO definite shape; takes
the shape of container.
Gas
State of matter with NO definite
shape or volume; fills any container.
Texture
The way something feels. Cotton feels
soft and sandpaper feels rough.
Flexible
The ability to bend back and forth
without breaking. Wires are flexible.
Luster
How shiny things are. Things with high
luster reflect light. Things that have low
luster are dull.
Flammable
Ability to burn.
Elastic
The ability to stretch. Rubber bands are
very elastic.
Weight
A measure of the pull of gravity. Spring
scales are used to measure weight.
Vibration
Conductors & Insulators
Conductor
Allows energy to go through it. Copper
wires allow electricity to pass through
them. Pots for cooking allow heat
energy to pass through them so you can
heat up food.
Insulator
Does NOT allow energy to pass through
it. Rubber gloves do not let electricity to
pass through. Pot holders and insulated
gloves don’t let the heat from a hot dish
go through them.
Mixtures & Solutions
Mixture
Combination of two or more things that
keep their own properties. They can be
separated easily.
Solution
A special mixture created
when two substances mix
together evenly and share
properties.
Dissolve
A process. When a solid mixes evenly
with a liquid.
Soluble
Ability of a substance to dissolve in
water. They are used to create
solutions.
Back and forth movement that
causes heat and sound.
Magnetism
Ability to attract iron, nickel, and cobalt
Buoyancy
The ability to float.
Density
How much matter there is in a given
volume. It determines buoyancy. Gases
have less density than the other states
of matter.
