Yes just a physical change
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.
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.
putting water in to the refrigerator to freeze it cutting wood dropping plates, or cups chopping fruits or vegetables tearing paper breaking items chewing pencils peeling potatoes
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, it's the equivalent of chopping wood in half, which is also a physical change. Unlike chopping wood in half, this change is completely reversible.
Chopping firewood is a physical change, not a chemical change. The act of chopping firewood only changes the size and shape of the wood, but the chemical composition of the wood remains the same.
Chopping wood is a physical change because the wood is being physically broken down into smaller pieces without changing its chemical composition.
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.
Chopping wood for a fire is a physical change because the wood's size and shape are altered. Burning the wood is a chemical change because it undergoes a chemical reaction to produce heat, light, and other byproducts.
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.
physical because the cork is still a cork

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.
