Yes, cutting a tree into paper is a physical change because the tree's form is being altered without changing its composition. The paper still consists of the same material as the tree (cellulose), just in a different form.
It is a physical change, as the chemical integrity remains the same.
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
Psychical change because you're not changing the chemical make-up of the piece of paper, just dividing it. Think of it like cutting an apple. You can only cut it so many times before it's a chemical change.
No. It is a physical change because there is no change in the chemical composition of the paper. If you were to burn the paper, that would be a chemical change called combustion, which would turn the paper into carbon dioxide and water, with the release of heat.
Yes, when you cut down a tree and it decomposes or is burned, the carbon stored in the tree is released back into the atmosphere as carbon dioxide. This contributes to the increase of carbon dioxide levels in the atmosphere, a greenhouse gas that contributes to climate change.
Physical
No, it is a physical change, the paper's molecules are not changing.
yes
It is a physical change, as the chemical integrity remains the same.
You can cut it and tear it up
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
Yes, cutting a sheet of paper in half is a physical change because the paper's properties, such as its shape and size, are altered, but its chemical composition remains the same.
Physical, because the paper hasn't changed any chemical properties (It is still paper), even after you cut a heart out of it.
Psychical change because you're not changing the chemical make-up of the piece of paper, just dividing it. Think of it like cutting an apple. You can only cut it so many times before it's a chemical change.
No. It is a physical change because there is no change in the chemical composition of the paper. If you were to burn the paper, that would be a chemical change called combustion, which would turn the paper into carbon dioxide and water, with the release of heat.
Cutting paper is a physical change because, it involves changing something without changing its chemical structure
the physical change is the change that you can not hear see or fell. ex she cut her hair, or your heart is beating faster.
