A chemical change
Because it takes plave in an oven and the yeast is rising without human help
Yeast causes both physical and chemical changes to bread dough. It digests sugars which produces gas (chemical changes,) which in turn lifts the dough's mass (physical change.)
No, because the dough is a solid, and the bread when it's done is a solid. But if you cook the bread too long at a high temperature, it will turn to ash, which WOULD be a physical change.
A chemical change because it causes the bread to rise. Also, the yeast can't be changed back into its original form after the change took place.
I think it's Chemical Change

physical. the water being added simply soaks through the coffee, so there's no chemical change.
chemical
Melting of ice with salt is example of physical change as there is no chemical reaction involved .

it is a chemical change
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)
It is a physical state change from a solid to a liquid. It is not a chemical change, unless other ingredients are then added when melted - as usually happens when used in cooking, for instance.
Physical because we can still seperate the particles
