Is this a physical or chemical change? Why? ww2010.atmos.uiuc.edu
Physical Evaporation It is changing the state of matter but not the fact that it is matter.
Is this a physical or chemical change? Why? Splitting of water into Hydrogen and OxygenSplitting of water into Hydrogen and Oxygen
Chemical Once the H and O are split apart they do not have the same chemical composition of water anywhere.
Is this a physical or chemical change? Why?
Chemical Once paper is burned it becomes a new substance, ash
Is this a physical or chemical change? Why? Ripping Paper
Physical The girl is changing the shape of the paper but not the chemical composition of the paper.
Is this a physical or chemical change? Why?
Physical The car’s dent caused a change in the shape but not the chemical composition
Is this a physical or chemical change? Why?
Chemical The chemical composition of the metal has changed to form rust.
Is this a physical or chemical change? Why? Melting Metal
Chemical The composition of the metal has changed due to the addition of heat to the metal.
Is this a physical or chemical change? Why? Bending Metal
Physical You change the shape of the metal but the chemical composition.
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 Metalloid
It does not belong due to it’s position on the periodic table. It goes down in a stair step fashion. The other 3 go straight down in columns on the periodic table.
Which word does not belong? Why? Volume Flammability Combustion Tarnishing
volume Volume is a physical properties The other three are chemical properties
Which word does not belong? Why? Conductivity Metal Shiny luster Gas
Gas is not a property of metal
Which word does not belong? Why? Water Displacement Milliliter Mass Beaker
Mass Mass is measured in grams. The other three measure in volume.

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.
