Which word does not belong? Why?
• Evaporation• Spoiled Milk• Freezing• Soluble
Spoiled Milk
• The other three are physical change.
• Spoiled Milk is a chemical change.
Which word does not belong? Why?
• Noble Gas
• Groups
• Similar Properties

Look at the Pictures. Do you think a chemical or physical change took place. Explain why.
Chemical Change• 1. The condensation on the side
of the third baggie tells us there was a heat increase.
• 2. The expansion of the baggie also tells us that gas was produces.
