Physical Change

• Atoms do not rearrange (switch partners)
• Only physical properties change. Chemical properties do not change
• Physical changes are generally easy to reverse
• No energy is produced by the substance.

Chemical Change

• Atoms are rearranged into different molecules. There will be a new chemical formula
• Both physical and chemical properties are changed
• Changes are not reversible without another reaction
• Energy is often produced ( fire or heat, for example)

Physical vs. Chemical
Physical change is like printing the same word in a different style of type:
stampedes stampedes
Chemical change, or chemical reaction, is like scrambling the letters of a word to make new words:
stampedes made + steps
