Spark is a chemical process; a material particle is burned and burning is oxidation - chemistry.
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
No, flammability is a chemical property, not a physical change. Flammability refers to a substance's ability to undergo combustion when exposed to a flame or spark, which involves a chemical reaction where new substances are formed.
Yes it is a chemical change because color change is an observed change that a chemical change has occurred. So you are very much right. :)
physical. the water being added simply soaks through the coffee, so there's no chemical change.
It's so physical ! Because is a property indepedent of chemical changes.

I belive so.

Rusting is a chemical process, so no if its lacking it cannot be chemical its physical
its a physical joking its a chemical change a physical is one substances, and a chemical change is two or more substances so the answer is to food molding a chemical change
It is as irreversible change, so it is chemical.
Physical... chemically, it's still the same substance,
Oxidation is a chemical reaction, so it is a chemical property.

chemical,because if you combined them you can't take it back out so it is in there for good so it is chemical
Chemical (So says my science book for school)
physical. the water being added simply soaks through the coffee, so there's no chemical change.
