• John 1:3–“All things were made by Him; and
without Him was not any thing made that was made.”
God gave matter characteristicsGod gave matter characteristics
• PHYSICAL PROPERTIES– Characteristics of a substance that can be
observed without changing the identity of the substance.
• Examples:– Color– Smell– Texture
States of Matter States of Matter
• One physical property of matter
• All matter is composed of tiny particles that are always in motion.– Attract each other– The strength and motion = state of matter
SolidSolid
• A substance that as a definite volume and shape.
• The particles in it vibrate, but do not move much.
• It has strong attraction in its particles keeping their shape.
LiquidLiquid
• A substance that has a definite volume but not a definite shape.
• It takes the shape of its container.• The particles move more than the particles in
solids do.• Attraction in its particles is still strong enough
to keep it from spreading apart.
GasGas
• A substance that does not have a definite shape or a definite volume.
• It takes the shape of its container.• It can expand to fill the volume of the
container.• Can be compressed, particles are very active.• The attraction is weak.
PlasmaPlasma• Fourth state of matter• Occurs only at very high temperature.• Found on the sun, lightning bolt• Man-made plasma causes fluorescent light to
shine.
Changing States of Matter Changing States of Matter • PHYSICAL CHANGE
– Change in matter that does not form a new substance.
– Change from one state to another.
• FREEZING POINT– The temperature at which a substance changes to
a solid.
Melting point and freezing point of a substance are the same temperature.
VAPORIZATIONVAPORIZATION
• The process of a liquid changing into a gas.• BOILING – when bubbles of gas rise and break
away from the liquid’s surface.
• BOILING POINT– The temperature at which liquid changes into gas.
Substances have different boiling points.Ex.
Boiling point of water is 100°C.
• EVAPORATION – another form of vaporization.– A substance evaporates when it changes from
liquid to gas below its boiling point.
