Exothermic. It release heat in the process.
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
endothermic because the energy is absorbed
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.
An endothermic reaction is a reaction where heat flows from the surroundings in to the system. Holding an cold pack to your skin is an endothermic reaction; heat flows from your skin (surroundings) into to the cold pack (system).
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.
The reaction is endothermic.
The reaction is exothermic.
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.

endothermic because the energy is absorbed
A hand warmer is typically called a "hot pack" or "heat pad."
Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.

An endothermic reaction takes in heat from its surroundings. One example of a spontaneous endothermic reaction is an ice pack that doesn't have to be kept in the freezer. When the ice pack is struck with your palm the membrane is broken and the salt is dissolved in the water. The equation would be NH4NO3 plus H2O is equal to NH4 plus NH3.

Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
