Chapter 2: Matter

Matter

Anything that has mass and takes up space

Physical Property

Any property of matter that can be observed or measured without altering a substance’s chemical composition

Chemical Property

Properties that describe how matter acts in the presence of other materials or how it changes composition under certain conditions

Intensive Physical Property

Do not depend on the amount of material present; Density, Malleability, Ductility, Conductivity, Color, Texture, State of matter, Shape, Odor, Taste

Density

The amount of matter in a unit volume (d=m/v)

Malleability

Materials that can be hammered into thin sheets or shapes

Ductility

Materials that can be drawn into long thin wiresC

Conductivity

Ability to transfer heat or electricity

Extensive Physical Property

Property that change depending on how much of the material is present; Mass, Volume, Length

Reactivity

Relates to how a substance responds to different substances or conditions

Flammability

Whether a substance will burn or notT

Toxicity

How much damage a substance will do to a particular organism

Physical Change
