slicing bread is considered a physical change because the bread is still bread after it is sliced. A chemical change for bread is the ingredients mix together to make bread
It is a physical change
It is a physical change
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.
Physical
Yes, it is. The process by which heat changes the molecules of the bread from white and soft to brown and crispy is a chemical change. A chemical change does NOT mean you have to add chemicals. It just means the chemicals (molecules) in the substance changed their chemistry. So slicing bread is a physical change, but toasting it is a chemical change.
Slicing bread is a physical change, because each slice of bread has the same chemical composition as it had before it was sliced.
Slicing bread is a physical change because it does not change the chemical composition of the bread.

Slicing turkey represents a physical change, not a chemical change. The chemical composition of the sliced turkey is identical to the chemical composition of the intact turkey. Only a physical change has taken place.
This is a physical change. You only change the shape and size of an apple by slicing it. Chemical changes would mean changing the molecular composition of the apple.

Picking tomatoes from a plant a physical change or chemical change
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
