A decrease in temperature is a physical change, not chemical.
Something that burns or is flammable would be a chemical change.
Something that burns or is flammable would be a chemical change.
When something is being burned and turned into ashes, it would be a chemical change.
If you created something new. If you combined 2 chemicals and there was a line of lets say yellow in the middle, the yellow line would be the chemical change because you have created something new.
Type of cake and list of ingredients would be needed. Possibly an acid causing a chemical change in something. Bananas or apples could darken the batter.
Chemical, When something changes in color, it is a sign of a chemical change.
I would think it to be a Physical Change. Not chemical.
Stating that something is flammable is stating a chemical property. But the actual burning would be a chemical change.
Its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical.
I suppose that would be a summary of a change which is not chemical. Perhaps it would be something like ice --> water
Unless you overdo it and carmelize it, it is a physical change. A typical process is to dissolve a large amount of sugar into hot water (physical change - the sugar is still sugar and the water is still water; they do not react. If the sugar-water is not syrupy enough, you can boil off some of the water (still a physical change). If you overdo it though, you will begin to caramelize the sugar. If the sugar is sucrose, it breaks down into fructose and sucrose along with a host of other side reactions that condense, isomerize, dehydrate, fragment, polymerize, and otherwise chemically change the original sugar. Caramelization is definitely a chemical change, but it is not necessary to make syrup.
Yes it is a chemical change because when you burn paper it cannot be reversed. If it had been a physical change then you would have been able to reverse what you have done to the paper, by turning it back to its original state.
