endothermic because the energy is absorbed
its an endothermic reaction
It is an example of an endothermic reaction. It is absorbing heat.
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
Instant cold packs use water and ammonium nitrate. The ammonium nitrate is a powder found inside the cold pack, and the water is inside a plastic container inside the cold pack. When the plastic container containing the water is broken and mixed with the ammonium nitrate, the water dissolves the ammonium nitrate, which is overall an endothermic reaction, causing the cold pack to get cold.

The idea of nuclear fusion occurring at room temperature is called cold fusion.
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold.

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.

C An endothermic reaction is occurring, transforming chemical potential energy into thermal kinetic energy.
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.
When ammonium nitrate (NH4NO3) is mixed with water, the dissolution of ammonium nitrate occurs - that is, it is broken up into its ions. This is endothermic, and is the driving reaction behind instant cold packs.
A flame cannot be any cold but always hot even at the first instant it is lit.
