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

its an endothermic reaction
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.
