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.
its an endothermic reaction
It is an example of an endothermic reaction. It is absorbing heat.
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.
In cold packs is usedAmmonium nitrate. It's dangerous because it can explode. But for this it must be absolutely dry.In a cold pack it is in a water solution. Nevertheless you shouldn't eat it or contact it a long time with your skin. In case of a damage of the cold pack you can just wash it away with water.
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.

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.
Yes. It is possible to be poisoned by an ice pack.
Just below freezing is ideal

the chemicals inside react to create the cold
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.
