Properties of Matter Section 3.1

What is Matter? Matter – anything that has mass and volume Everything you can see and touch is made of matter Only things that aren’t matter are forms of energy – light and sound. https://www.brainpop.com/science/matterandchemistry/measuringmatter/preview.weml

Mass Mass – the amount of matter in a substance or object. SI units – grams, kilograms

Mass vs. Weight The more matter an object contains, the more it weighs. Weight – a measure of the force of gravity pulling on an object. A scale is used to measure the force pulling down SI unit – Newton (N) Example: 1kg weighs 9.8 N (2.2 lb)

Volume Volume – the amount of space matter takes up Liquids measured in graduated cylinders. Irregular shaped objects use water displacement. Measured in liters, mL, m3, cm3

Displacement Method

Properties of Matter Physical Properties Examples describe matter without changing its identity Examples color, shape, size, density, melting point, and boiling point

Physical Properties

Density Density – physical property, represents how tightly packed particles of matter are. D = Mass/Volume

Chemical Properties describe how a material will react to form something new Examples flammable (can burn) can corrode (metals combine with metals  dull, brittle can sour forms precipitate (solid forms from 2 liquids) reacts with acid effervesces (forms bubbles of gas, NOT BOILING)

Reactivity Reactivity – the ability of matter to combine chemically with other substances. Example – iron reacting with oxygen to produce rust.
