no physical change is ptting ice cream and milk and mixing it for a milkshake or burning a piece of paper.
grass growing is a physical change.
It is a physical change because it is still grass. Nothing new has been made.
Lichen growing on tree bark is a physical change. The process involves the physical attachment of the lichen to the bark's surface, without any change in the chemical composition of the bark or the lichen itself.
Chemical. Because this affects your brain.
First of all lets understand Physical & Chemical Change. Physical change can be reversed and the chemical properties of the two states remain the same. Chemical change cannot be reversed and the chemical properties of the two state are entirely different. Now lets get back to the question. Is growing a tree a physical or a chemical change. The growing of a tree requires chemical changes, primarily the conversion of water and carbon dioxide into cellulose and oxygen. So the growth results primarily from chemical changes.
Flowers blooming, trees growing, plants sprouting
grass growing is a physical change.
physical change
no
Plant growing involve physical and chemical changes.
It is a physical change because it is still grass. Nothing new has been made.
Plants change through a phenomenon called a tropism. Some examples include a positive phototropism (growing toward a light source) and a negative gravitropism (growing upward, against gravity).
Lichen growing on tree bark is a physical change. The process involves the physical attachment of the lichen to the bark's surface, without any change in the chemical composition of the bark or the lichen itself.
Since a physical change is something that happens to you, then you and any living thing is involved in a physical change. For example, if you are growing, you are involved in that physical change, because it is happening to you. Hope this helped!!
Growing vegetables can be a chemical process. However it is most likely that growing vegetables is a physical process because the chemical composition does not usually change.
