Describing Matter. Reviewing MATTER Matter: anything that has mass and takes up space – Mass – the amount of matter in a substance – Volume – the amount.

A Physical Property is a property that can be observed without changing the make up of the substance. You just look at it - or measure it. Examples are:

Physical And Chemical Properties

Properties Properties are descriptions of matter. There are 2 types of properties…

Physical Properties Identified easily. It is what it is. NO CHANGE to chemical structure. Color (red, yellow, etc.) State (solid, liquid, or gas) Odor (odorless, smells like eggs, etc.) Hardness (hard, soft, squishy) Density (amount of mass in a given amount of space) Volume (amount of space an object occupies) Freezing Point Boiling Point

Physical Properties List 3 Physical Properties of the following objects:

Chemical Properties Identified only by CHANGING the substance’s chemical identity. 1. Flammable/Nonflammable 2. Combustible/Noncombustible (burns or doesn’t burn) 3. Corrosive/Noncorrosive (can be destroyed slowly by chemical action) 4. Rusts/Does not rust 5. Reactivity

Reactivity Different substances react differently to other substances. If two substances REACT chemically to each other, we say the substance has reactivity to that substance. Sodium metal is reactive to water!!
