This question is extremely general (no offense) but if by you mean "see stuff" you mean producing a new substance, then yes, it is a chemical change.
It is a physical change because no new stuff was created. NO it is not a chemical change.
yes, cooking is a physical change. Mostly stuff that are cooked are chemical changes
Soda is not a chemical change it does not change in color, flavor, and texture if it's a chemical change it would do that stuff to change but it isn't read this definition a chemical change is a change that produces new substances with new properties

Heating a wood splint is a chemical change. If this was done in something like a test tube, you will see many things occur that indicate this. First, you will see a werid kind of smoke, the splint turning into black stuff, and a really bad smell. Well the smoke is CO2 and the black stuff is ash from the burning. Because there is a new substance being made and the identity of the original substance(your splint) has changed, the reaction is chemical.
when there is a color change, formation of a gas, formation of a precipitate, and by an energy change (exothermic and/or endothermic).
There are signs that you can see when a chemical change takes place. It is true that fizzing or foaming is evidence that a chemical change may have occurred.
