PropertiesofMatter

Properties All matter has Properties (qualities or characteristics to describe it). Properties of this metal: shiny malleable conductive silver color

There are two types of properties:PhysicalPropertiesChemicalProperties

Physical Properties can be observed without changing without changing the matter: shape state (solid, liquid, or gas) density color smell appearance

Physical Properties of this ball: round shape solid red color no smell

Chemical Properties can only be tested by changing by changing the matter: flammability (will it burn?) oxidation (will it rust?) volatility (will it explode?) reactivity (will it react to chemicals?)

Chemical Properties of this flask: not flammable not flammable won’t rust won’t rust can explode if can explode if over heated won’t react to acid won’t react to acid

Physical Properties What are some Physical Properties for this hamburger? solid round bun many colors smells tasty average density

Chemical Properties What are some Chemical Properties for this hamburger? can burn (except lettuce and pickles) won’t rust won’t explode will react to stomach acid by dissolving

Physical Properties What are some Physical Properties for propane gas? gas no fixed shape invisible Smells like rotten eggs very light density

Chemical Properties What are some Chemical Properties for propane gas? will burn easily gas won’t rust (but tank will) can explode! can react with other chemicals
