The process described is endothermic. An endothermic reaction absorbs heat energy from its surroundings, which results in a drop in temperature in the environment. In this case, the cracking of the ice pack initiates a reaction that takes in heat, leading to a decrease in temperature both in the ice pack itself and in the surrounding area. Because the environment loses heat energy, the overall process is characterized as endothermic.
An ice pack is cracked, starting a reaction. The ice pack decreases in temperature as the reaction absorbs heat energy from the environment. The temperature of the surroundings decreases as heat is absorbed by the ice pack. Is this process exothermic or endothermic? Explain your reasoning in 3-5 sentences
