Answer :
Answer:
D. The reaction absorbs energy from its surroundings
Explanation:
Cold packs have an endothermic chemical reaction. In an endothermic reaction energy is absorbed by the system from the surrounding. Exothermic reaction releases energy from the system into the surrounding. If a pack had a chemical reaction such that the reaction released energy into surrounding then it would be a hot pack.
In the given scenario, the reaction absorbs energy from its surroundings. The correct option is D.
What is endothermic reaction?
Any reaction mechanism that soaks up heat from its surroundings is an endothermic reaction.
The absorbed energy serves as the activation energy for the reaction to take place.
The reaction mechanism of cold packs is endothermic. In an endothermic reaction, the function is to absorb energy from its surroundings.
Exothermic reactions expel energy from the system into the environment.
A hot pack is one that has a chemical reaction that releases energy into the surrounding environment.
An exothermic reaction is a chemical reaction in which energy is released in the form of heat or light. These are the inverse of endothermic reactions.
Thus, the correct option is D.
