Cold Pack

Cold Pack
When you activate an instant cold pack, water mixes with a chemical and the pack gets very cold?

This is an example of

a. an exothermic reaction
b. an endothermic reaction
c. a combustion reaction
d. a physical change

I’m pretty sure its not c.

its the definition of an endothermic reaction that the surrounding gets cold so its

b. an endothermic reaction

Make an Instant Cold Pack from Sodium Acetate.
