The reaction is endothermic.
Yes, the activation of a cold pack is endothermic. It absorbs heat from the surroundings in order to lower the temperature of the pack and create a cooling effect.
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.
C An endothermic reaction is occurring, transforming chemical potential energy into thermal kinetic energy.
Exothermic/endothermic is a process not a feeling.
Endothermic reactions absorb heat from their surroundings, making them feel cold.
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
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
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.
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.
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
Water and ammonium nitrate. When you break the tube of ammonium nitrate inside, it mixes with the water to cause an endothermic reaction that absorbs heat. That's why it gets cold.
