No..if hat was true. People who drank tons of water a day would have no teeth!!!
Sugar reaches the copper and they form a physical change
You should just soak a PENNY in CoCA CoLA.
i did a science project on it and all it did to the penny was stain it but i dont know because i just let it sit in the coca cola but maybe if you scrubed it with something maybe be but i tested it and it just stained it
coca-cola has a high acidic content, and prolonged exposure can erode the enamel on the teeth
water
Coca-Cola does not have any effect on amalgam. However, it does contain ingredients that can erode the enamel on your teeth if you do not brush them regularly.
Tap water freezes faster than Coca Cola, orange juice, and salt water. Salt water will freeze at a lower temperature due to the presence of salt, while the sugar content in Coca Cola and orange juice also lowers their freezing points compared to plain tap water.
a ice cube in alcohol would melt fastest because of the heating molecules contracting with the ice cube molecules
No
Coca-Cola leaves the penny bright and shiny. Coke does this by corroding the copper oxide layer that forms naturally through exposure to the air over the penny's copper plating. While the oxide layer is stable and prevents further reaction of the copper plating, it obscures the shiny copper plating to give the penny a darker, dull appearance. Coke is able to remove the oxide layer on pennies because of its acidity (Coke has a pH of approximately 2.5, similar to lemon juice). Acidity gives it corrosive properties. To be more specific (and a tad uncertain), the phosphoric acid in Coca-Cola likely reacts with the copper oxide layer to remove it.
Both work but Coca Cola is the best
