Which of the following is an endothermic process? a. rusting a nail in water b. mixing strong hydrochloric acid and strong ammonium hydroxide c. a heat pack d. a cold pack, cooling

Hello There!

A Heat Pack is An Example Of A Endothermic Process.

An Endothermic Reaction Is A Reaction That Requires Energy To Move Forward.

An endothermic process is D. a cold pack, cooling.

Endothermic reaction is that type of chemical reaction that requires heat from the surrounding for the reaction to occur. It basically draws heat from the environment to imitate the reaction. The process of using a cool pack for cooling is also an example of endothermic reaction as the heat is absorbed from the surrounding object by the cool pack.

Due to this heat, the ice in the cool pack begins to melt. This process is considered endothermic because the physical change in state of ice into water is not possible without the heat from the surrounding.
