i believe it is chemical because it cannot be returned to its original state.
Slicing bread is a physical change because it does not change the chemical composition of the bread.
chemical
Flour eggs is physical and yeast to bread chemical
Physical cause it is still bread
chemical
Yeast rising bread works because yeast (an organism) converts starch to carbon dioxide which makes bread grow. This can be seen as a chemical reaction (yeast converting starch to CO2 gas) or a physical reaction (the CO2 making the bread expand).
A chemical change Because it takes plave in an oven and the yeast is rising without human help
Slicing bread is a physical change because it does not change the chemical composition of the bread.
Slicing bread is a physical change, because each slice of bread has the same chemical composition as it had before it was sliced.

No, slicing bread is a physical change. The act of cutting the bread into smaller pieces does not alter its chemical composition.
