Flour eggs is physical and yeast to bread chemical
If you mean ground flour, then no. Grinding flour is a physical change because there is no change in chemical composition.
It is a PHYSICAL change.
No. It is a physical change because the wheat's chemical composition does not change.
Physical reactions: freezing, boiling, evaporation, condensation etc. Chemical reactions: eg. heating, baking, decomposition etc. Physical mixtures - mixtures in which the substances are easy to separate and get back (done by physical reactions) eg. flour and rice grains - you can sieve them. Chemical mixtures - mixtures in which the substances are hard to separate and get back (done by chemical reactions) eg. cakes - u cant get the eggs and other stuff back.
physical
This is a chemical change because it has all the characteristics of one. The color changes, the texture changes, new stuff is created, and you can't separate by physical means. It is chemical.
Mixing flour and baking soda is a physical change; the process of mixing them together does not in itself cause them to change into any other chemical. However, when the pastry is baked, then there will be chemical changes.

Physical, the chemical properties of the wheat are still the same.flour is ground by a physical change
Physical change
It is not a property; it is a physical process.

Flour is not a change of any sort. It is a mixture of organic compounds.
To call it an physical or chemical change, we first need to describe both of them briefly. A physical change is the one which does not change the chemical properties of a substance. A chemical change is the one which changes the chemical properties of a substance. Whether they can be recovered or not is not of importance here. So if you mean to dissolve some powder in hot water such that it does not make any reaction with water, then its a physical change. (Mixing flour or salt or sugar powder are examples) However if you put some powder in hot water which creates a reaction and the molecules of that powder are no longer the same, then it would be a chemical change. (Adding tiny sodium or potassium pieces to water are examples)
It is a PHYSICAL change.
By mixing wet and dry ingredients there will be a chemical reaction.For instance preparing pancakes, when mixing flour,sugar,salt and baking soda with grease,eggs, vinegar and milk these combined will form a solid pancake.
