The process described in the ice pack is endothermic. In an endothermic reaction, the system absorbs heat energy from the surroundings, resulting in a decrease in temperature of the environment. In this case, as the ice pack undergoes a reaction and cools down, it is pulling heat from its surroundings, which also causes the temperature around the ice pack to drop. This energy absorption indicates that the reaction requires heat from the surroundings to proceed, characteristic of endothermic reactions.
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.(4 points)
