Physical Properties

Using our senses- Color

There are two pitchers of liquid on a picnic table- one is water and the other is lemonade-

They are not marked.

How do you know which is which?

Physical Properties

A characteristic of an object or substance that can be observed, described, measured by changing the matter.

Using our senses

Honey is viscous, or thick, sticky-

Between a solid & a liquid

Changing the state of matter can tell us about its properties.

Water is a liquid, but can be solid as ice, and a gas as steam

Thermal Conductivity - The ability to transfer energy (heat) to something else

Coffee cups built to prevent the coffee from burning the person holding it.

Solubility-

The ability of a substance to dissolve into one another.

Like sugar dissolves in coffee.

Malleability

The ability to hammer a solid without shattering it or braking it's shape

The process of separating mixtures - helps use understand physical properties.
