the chemicals inside react to create the cold
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.
The reaction is endothermic.
You can use ammonium nitrate to make a cold pack. When the salt dissolves in water, it absorbs heat from its surroundings, causing the pack to become cold.
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.
cold pack contains cold stuff like ice, hot pack stuuf like fire
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.
A cold pack is to make lumps go down and a heat pack is for when your sick.
The pack was going to kill Bella and Renesmee.
No.
the wolf pack in La Push doesn't have a name they are simply just 'the pack' to the boys.
Yes. It is possible to be poisoned by an ice pack.
Just below freezing is ideal

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.
Five in New moon but as the pack gets bigger in eclipseand breaking dawn when the pack gets to 11 wolves
Heat energy is transferred by conduction from the muscle to the cold pack.
