Question

What types of reactions take place in hot packs and cold packs? What evidence shows that

both hot packs and cold packs experience chemical reactions? Drag and drop the text into
the correct boxes.

Answer 1

Cold pack: absorbs heat (endothermic reaction)

Hot pack: releases heat ( exothermic reaction)

Step-by-step explanation:

when a cold pack/hot pack is shaken, water mixes with the chemicals in the outer layer and reacts to release or absorb heat.

Answer 2

reaction to cold pack: change in temperature

Evidence of a chemical reaction etc is change in composition

Explanation: composition is atoms changeing and etc, which is a chemical reacton i think. Change in temperture is alsoa chemical reaction but cold packs
