2 Physical Properties Viscosity Conductivity Malleability Hardness
Melting point Boiling point Density Ductility Magnetism

3 Viscosity: the tendency of a liquid to keep flowing – its resistance to flowing .
Greater = slower the liquid moves Viscosity usually decreases when heated

4 Conductivity Ability to allow heat to flow.
Those materials that have a high conductivity like metals are called good conductors. Usually means conductors of heat and electricity.

5 Malleability Ability of a solid to be hammered without shattering.
Most metals are malleable.

6 Hardness One way to compare is to see which material scratches the other. Diamond is the hardest mineral and Talc is softest.

7 Melting and Boiling Point
The temperature at which a substance changes from solid to liquid is its melting point. Water = 0° C The temperature at which a substance boils is its boiling point. Water = 100 ° C

8 Density

9 Physical Properties Some of the properties of the material change, but the substances in the material remain the same. Water from liquid to a gas during boiling Crumpling and slicing change size and shape. Some can be reversed (freezing and melting)

10 Chemical Properties Any ability to produce a change in composition of matter. Can be observed only when the substances in a sample of matter are changing into different substances.

11 Flammability Materials ability to burn in the presence of oxygen.
Sometimes not desirable property. Children's sleepwear. (flame-resistant) Materials that can burn are used for fuel.

12 Reactivity How readily a substance combines chemically with other substances. Oxygen is reactive easily with most other elements. Rust Nitrogen is not reactive and used on ships as a gas to decrease rusting.

13 Buoyant Force The upward force on an object immersed in a fluid.
If the buoyant force is equal to the object then it floats. If the buoyant force is less than the object then it sinks.
