Observing is when you notice something.
|
Ways you can notice something are by seeing, smelling, hearing, tasting, or feeling it.
|
|
Physical Properties are things you can observe without changing the chemical make up.
|
Examples are: Color, Shape, Length, and Smell.
|
|
|
States of Matter
|
Solid
Liquid Gas |
|
Texture
|
How smooth or rough something is.
|
|
|
Solubility:
|
Ability to dissolve in a liquid.
(If you mix sugar in a glass of tea, it remains sugar.) |
|
|
Ductility
|
How easy it is for something to be pulled into a wire.
|
|
|
Malleability
|
The ability to be pounded into thin sheets.
Example: Aluminum Foil has high malleability. |
|
Magnetism-ability to attract or repel metal
|
-All magnets have a north and south pole.
-Magnets have poles where opposites attract and the same poles repel each other. |
|
Luster
|
How much light an object reflects.
-Something that reflects a lot of light has a shiny luster. -Something that does not reflect light has a dull luster. |
|
|
Thermal Conductivity
|
is the rate at which a substance transfers heat (thermal) energy
If something does not transfer heat energy well, it is a poor conductor. Poor Conductors are good insulators |
|
|
Density
How much mass is in a given volume |
Layers on top- less dense
Layers on bottom- more dense |
|
Density= mass/volume or
D= M/V |
To find an objects density you must measure its mass and volume.
|
|
Hardness
How easily something will scratch |
Moh's scale is used to measure hardness.
|
|
|
Physical Change
change that can affect one or more physical properties of a substance. |
changes do not change the identity of the matter, they still have the same properties as they did before the change happened.
|
|
If you break a piece of chalk, is it still chalk?
|
Yes. Only the size of the chalk changes.
Physical Change Examples: Freezing water to Ice Cutting your Hair Mixing Oil and Vinegar |
