Question

Cold packs are designed to become very cold when activated. When the pack is activated, a chemical reaction occurs to make the temperature of the cold pack decrease. What must be true of this chemical reaction? (2 points) The reaction releases energy to its surroundings. The reaction releases energy to its surroundings. The products and reactants have the same amount of energy. The products and reactants have the same amount of energy. The products have less energy than the reactants. The products have less energy than the reactants. The reaction absorbs energy from its surroundings.

Answer 1

The reaction absorbs energy from its surroundings.

Step-by-step explanation:

An endothermic reaction is any reaction in which energy is absorbed by the reaction system.Thus implies that energy is withdrawn from the environment A cold pack's function is based on an endothermic chemical reaction.

The absorption of energy by the reaction system means that the environment feels cool in an endothermic reaction.This manifests in a decrease in the temperature of the cold pack.
