How does breaking cold pack release cold?
the chemicals inside react to create the cold
Who invented instant cold packs?
The first of the instant cold packs was a liquid-type invented by Albert A. Robbins and patented August 11, 1959. Robbins' "Chemical Freezing Package" involved and outer pouch containing two separate compartments for water and ammonium nitrate that would mix and freeze when the user split a perforation between the two - say by hitting or snapping the package as we would with the modern variety. Robbins' patent was assigned to Kwik-Kold of America. Parent company Cardinal Health continues to market this, and the more recently invented gel-type cold packs, to this day.
Is a cold pack an endothermic reazction?
The reaction is endothermic.
What are the advantages of cold therapy gel pack verses ice pack?
Mix critic acid and sodium and bicarbonate
Which compound could you use to make a cold pack?
Sudden crystallization of a supersaturated solution. This is a physical phase change, not a chemical change.
How can we make an efficient instant cold pack by using ammonium nitrate and water?
egg
When you activate an instant cold pack water mixes with a chemical and the pack gets very cold This is an example of?
its an endothermic reaction
How is energy transferred when an instant cold pack is put on muscle injury?
Heat energy is transferred by conduction from the muscle to the cold pack.
How is energy transferred when an instant cold pack is put on a muscle injury?
Heat energy is transferred by conduction from the muscle to the cold pack.
Can you refreeze or refrigerate an instant cold pack?
can you refreeze cold packs
What type of reaction is occurring when you activate an instant cold pack?
endothermic because the energy is absorbed
Should cold pack or heat make a lump down?

Explain which type of reaction exothermic or endothermic would be required to make a cold and a cold pack or hot pack?
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.
Where is the pack-a-punch on the ascension zombie map?
you can only go to the pack a punch room when the rocket lauckes then under where the rocket was is the pack a punch room
What can be mixed to produce a very cold effect that doesn't give off an unsafe gas?
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.
When you activate an instant cold pack and water mixes with a chemical and the pack gets very cold what example is this?
It is an example of an endothermic reaction. It is absorbing heat.
What are 'cold pack' and 'hot pack'?
cold pack contains cold stuff like ice, hot pack stuuf like fire
