A decrease in temperature has moved the algae into the stream.
No. Change in odour is likely to be related to a chemical process.
Very probable a chemical change; but also physical changes can be the cause.
In which country are the people least likely to change their physical environment?
It is a physical change unless it is caught on fire to mold into a different shape then it would be a chemical change. The substance that does change shape does not develop new chemical properties.
Crushing the graham crackers is a physical change, not chemical. *Chemical reactions and chemical changes are the same thing.
Eggs turning into an omelette is a chemical change. When you cook eggs, they will most likely bubble or fizz. Bubbling or fizzing is a sign of a chemical change. Also, once the egg is turned into an omelette, you are never able to change it back into an egg. Physical changes are reversible, and chemical changes are not easily reversed. Eggs turning into an omelette is a chemical change. Hope I helped :)
it can be both, but more likely is it a chemical change.
If the sheet is turning into a pillowcase, it would be a physical change. The sheet is not changing anything but its shape to become a pillowcase, and it most likely can be reversed to turn back into a sheet.
it can be both, but more likely is it a chemical change.
It would be a physical change because you are changing the shape of the wood not the chemical composition of the wood. However, you could possibly create a chemical change if you could hammer hard and long enough to burn the wood. Not likely, but it is possible.
chemical weathering change will most likely make a new substance
The nurse does. You go to her office and ask for a diaper change and she will most likely do it
