  Evidence of Physical 
    verses Chemical 
        Change 
 VOCABULARY – physical properties, 
 chemical properties, physical change, 
 chemical change, chemical reaction,
 Law of Conservation of Mass
 Physical Properties 
 All matter has both physical and chemical 
 properties useful to scientists in the 
 classification of it. 
 Typical physical properties we will consider are: 
 color, odor, density, hardness, solubility, phase 
 of matter, melting points or boiling points.  
 Chemical Properties 
 These are determined by the reactivity 
 of a substance with another substance.  
 Examples: acidity or basicity 
 reactions with oxygen or other gases
 What properties cause A to react with 
 B to possibly form AB? 
  Caution: do not get hung up on the nuisances between these two.  
  Simply refer to the definition as defined here in class.
 Physical Change 
 This occurs if the shape, size or physical 
 state is changed, but the chemical 
 composition remains the same.
