endothermic because the energy is absorbed
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
This is an example of an endothermic chemical reaction, where energy is absorbed from the surroundings in the form of heat, causing the pack to become cold. The reaction between the chemicals in the instant cold pack and water absorbs heat from the environment, resulting in the cooling effect.
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
Endothermic reaction
A cold pack creates a endothermic reaction when the chemical reacts, which means that energy is taken from the surrounding, which makes the packaging cold. it is the opposite with a heat pack, an exothermic reaction is created which releases the energy into the surrounding creating the heat. Hope this helped.

Instant cold packs typically reach temperatures around 32-41 degrees Fahrenheit (0-5 degrees Celsius) when activated. This temperature drop occurs quickly due to a chemical reaction that absorbs heat from the surroundings, making the pack feel cold to the touch.
No, an instant cold pack contains chemicals that produce a cold reaction when activated, not the type of fuel needed for a rocket launch. Rocket propulsion requires specific types of fuel, oxidizer, and combustion mechanisms to generate the necessary thrust for liftoff.

Ice is cold, in the form of water put in a freezer. But some special reactions, such as Instant Ice, emit heat as the supercooling reaction releases energy.
Might be old or the water is too cold to activate it or too hot and killed it.
Instant cold packs cannot be reused once they are activated. The chemical makeup inside the package was created for one time use.
A reaction with water (hot or cold) is a chemical reaction.
A flame cannot be any cold but always hot even at the first instant it is lit.
C An endothermic reaction is occurring, transforming chemical potential energy into thermal kinetic energy.
