Lesson 3: How can Substances be Identified?

A property that describes whether a substance can dissolve in another substance.

• brittleness

• reflectivity

• solubility

• bubbles

A characteristic of matter that can be observed or measured. (color, shape, size, etc.)

• group

• period

• hardness

• property

A property that describes how well a substance allows electricity to pass through it.

• electrical conductivity

• reflectivity

• thermal conductivity

• solubility

A property that describes substances that change from a shapeable, gray substance to a brittle, orange substance.

• burns

• solubility

• rusts

• bubbles

A property that describes whether a substance can be shaped or not.
