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.
cold pack contains cold stuff like ice, hot pack stuuf like fire
When a cold pack is broken, it initiates a chemical reaction between the substances inside the pack. This reaction absorbs heat from the surrounding environment, causing the pack to feel cold. Breaking the pack allows for the substances to mix and react, resulting in the release of cold temperatures.
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.
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.
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.
Heat energy is transferred by conduction from the muscle to the cold pack.
when you are done with it or when it stops being cold.
Ammonium nitrate and water are in separate compartments in the cold pack. To activate the cold pack, you break the compartments in the pack so the ammonium nitrate and water mix. The ammonium nitrate absorbs all of the heat, making the water ice cold.
