This is a chemical reaction.
Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
i know that its physical change because all you saliva is doing is making the food wet
Yes, because the preparation involve chemical processes.
Yes, it is true; this technology involve chemical processes.

Preparation of pure iron from iron ores involve physical changes but also chemical changes.
three physical changes of making a s'more would be breaking the chocolate, breaking the crackers, and chewing the s'more when it's in your mouth.
Bonds in the reactants are broken, and bonds in the product are formed.
