All about the physical properties of matter. Good fro Science 5 lectures.

2. Only God can create or destroy matter.Only God can create or destroy matter.
• John 1:3
–“All things were made by Him; and
without Him was not any thing
made that was made.”

3. 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

4. States of MatterStates 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

5. 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.

7. 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.

9. 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.

12. 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.

14. Changing States of MatterChanging States of Matter
• PHYSICAL CHANGE
– Change in matter that does not form a new
substance.
– Change from one state to another.

16. MELTINGMELTING
• Process of a solid changing into liquid.

17. FREEZINGFREEZING
• Process of a liquid changing to a solid.
• Can be described as SOLIDIFYING.

18. • FREEZING POINT
– The temperature at which a substance changes to
a solid.
Melting point and freezing point of a substance are
the same temperature.

19. VAPORIZATIONVAPORIZATION
• The process of a liquid changing into a gas.
• BOILING – when bubbles of gas rise and break
away from the liquid’s surface.

20. • BOILING POINT
– The temperature at which liquid changes into gas.
Substances have different boiling points.
Ex.
Boiling point of water is 100°C.

21. • EVAPORATION – another form of vaporization.
– A substance evaporates when it changes from
liquid to gas below its boiling point.

22. CONDENSATIONCONDENSATION
• The process of changing a gas to a liquid.

23. • CONDENSATION POINT – the temperature at
which a gas turns to a liquid.
