That's complicated. The wood is simply covered up, so that's a physical difference. Application of the paint is also physical, you are just putting it somewhere else. What happens as the paint dries depends on the type of paint. Evaporation of the solvent is also physical, but as gloss paint dries chemical changes happen to produce the permanent skin.
Yes, chopping a piece of wood with an axe is a physical change. The physical appearance of the wood changes as it is cut into smaller pieces, but the chemical composition of the wood remains the same.
Any idea is a non example of physical change.
Alpha and beta radiation would be blocked by a 2cm piece of wood because they have low energies and can be stopped by physical barriers like wood. However, gamma radiation, which has higher energy, may not be fully blocked by a 2cm piece of wood and may require thicker shielding.
Yes, chopping a tree is a physical change because it alters the physical appearance of the tree by breaking it into smaller pieces, but it does not change the chemical composition of the tree.
Well, isn't that a lovely question. When you build a chair from wood, you're using physical changes like cutting and shaping the wood, rather than chemical changes. Chemical changes involve altering the chemical composition of a substance, like burning the wood to create ash. Keep creating and exploring, there are no mistakes in woodworking, just happy little accidents.
Cutting a piece of wood is a physical change because the chemical composition of the wood remains the same before and after cutting. The change is only in the physical appearance and shape of the wood.

Yes, it is a physical change.

Physical. If you were to cut that piece of wood in half what would it be? Still wood. There would be no chemical change. Just a physical change.
said pop_singer17@yahoo.com...it is called a physical change because its just only a wooden stick and it doesnt change in color, texture,or substance. .just only in size...
Physical change.

It is a physical change from a rough to a smooth surface.
