"chemical"
usually secondary to biologic activity.
The act of burying garbage itself is not really a physical change. If the garbage was crushed, that would be a physical change. When the garbage decomposes in the ground, that is a chemical change.
no. Rotting fruit is just changing the form of the fruit not making an entirely new substance. So, it is a physical change. Sorry ... rotting is a chemical change - the bacteria and molds are "eating" the fruit and changeing it into the eqivalent of poo. Drying fruit would be mostly a physical change.
it depends. If u were beating it then it would be physical. But in most cases chemical!
This is a physical change: the bread is not being chemically altered, and would have the same nutritional value whether eaten from the loaf or the slices. It would, however, be difficult to exactly reverse this physical change because of the nature of the product.
It would be physical change.

maybe. Rotting of wood is a slow chemical process. Trying to cut up a tree with a small knife is slow, but that would be a physical change.

because of the color change and it reacted with oxygen
It would be a physical change because it is not changing the chemical composition.
It would be physical change.
No, it is a physical change. Burning the firewood would be a chemical change.
Physical changes and Chemical changes are both the same - this would be a reversible change.
A physical change. A chemical change would be, for example, burning clothes, or dissolving clothes.
No, it would be a physical change. During a chemical change, substance(s) are changed into different substances. An example of a chemical change would be the rusting of iron but a physical change would be freezing water; or in this case, evaporation.
