Cornstarch is hydrolysed with hot water (adding also a small volume of sulfuric acid).
The product is glucose.
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
Well, there is no chemical reaction, really, since the cornstarch still remains cornstarch. (and if you dry it, it becomes cornstarch again) It's just that the cornstarch lightly bonds to the water which then lightly bonds to other cornstarch, creating a net-like substance. This net is easily broken and made, thus increasing the viscosity of the fluid and adding some other interesting properties to it as well.
Yes, when cornstarch is mixed with vinegar, it undergoes a chemical reaction. The reaction between the two creates a substance known as a suspension, where the cornstarch particles are dispersed in the vinegar, resulting in a thickened mixture.
A reaction with water (hot or cold) is a chemical reaction.
Heating is a chemical phenomenon.

No.
the earths mantle is very hot were cornstarch is not hot at all

No, because it just change to liquid
