a) Garbage rotting is a chemical change because the odour changed .
b) Cutting up carrots is a chemical change because it is hard to put back the carrots back, unless you have taped it or glued it which would be pretty nasty .
c) A silver spoon turning black is a chemical change because new colour changed.
d) Making tea from tea leaves is a physical change because it is just cutting tea leaves.
e) Bleaching a stain is a chemical change because of his change.
f) Boiling an egg is a chemical change because of the heat of the burners.
Hope it helps a lot!
-Physical change is the change in state but no new substance. Ex: Put your water bottle in the freezer in order to freeze and make it cold. So this is a change of liquid to solid.
-Chemical change is a substance changed/depended on a new substance with new/different properties. Ex: Putting salt/sugar on your glass of water. So the freshwater changed to salt water.
Clues for Chemical Change
-new colour produced
-heat/light is given off
-bubbles of gas are formed
-a solid material forms in a liquid which means precipitate
-changes to difficult to reverse. Ex: bread to toast.
