Cutting of trees is a physical change because there is not any change in molecular structure of trees.
Is cutting wood a physical or chemical change?
physical change means changes are reversable and no new substances must be formed . chemial changes are irreversable and new substances are formed . so here cutting would give rise to wood piece in which no new substance is formed so its physical change.
Why cutting is considered a physical change?
Cutting of a cloth piece is a physical change because it does not change the chemical composition of the cloth. However, it is an irreversible change because the cloth cannot be put back in the original state. Was this answer helpful?
What type of change is cutting down trees?

What is physical change and chemical change?
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
Is cutting of fruits a chemical change?
Fruit cutting is a physical change because no new substance is formed when the fruit is cut.
Is a tree growing a chemical change?

Is leaves falling a physical change?
Falling of leaves is not chemical change, its an example of physical change because no new substance is formed and is irreversible. There is no change in the chemical composition of the tree.
Is burning wood a chemical change?
The burning of wood leads to the formation of new substances like ash(carbon), carbon dioxide gas, water vapour, heat and light. This change is irreversible and hence a chemical change. While cutting wood into smaller pieces is a physical change as there is no change in the original composition of wood.
What are 5 examples of physical change?
Some common examples of physical changes are: melting, freezing, condensing, breaking, crushing, cutting, and bending. Some, but not all physical changes can be reversed. You could refreeze the water into ice, but you cannot put your hair back together if you don’t like your haircut!
What are the 5 types of physical changes?
Physical changes include transitions from one state to another, such as from solid to liquid or liquid to gas. Cutting, bending, dissolving, freezing, boiling, and melting are some of the processes that create physical changes.
What are three examples of physical change?
