Can you make a rocket with a instant cold pack?
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.
How does breaking cold pack release cold?
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.
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.
Why can't you refreeze instant cold packs?
Refreezing instant cold packs can damage the chemicals inside and affect their ability to provide cooling when needed. The components in the pack may not refreeze evenly or may not reach the required temperature for effective cooling after being frozen a second time. It is best to follow the manufacturer's instructions and avoid refreezing instant cold packs for optimal performance.
Is activation of a cold pack endothermic?
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.
What type of reaction is occurring when you activate an instant cold pack?
endothermic because the energy is absorbed
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.
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.
Can you refreeze or refrigerate an instant cold pack?
can you refreeze cold packs
Can you make a rocket with a instant cold pack?

When you activate an instant cold pack water mixes with a chemical and the pack gets very cold This is an example of?
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
When you activate an instant cold pack and water mixes with a chemical and the pack gets very cold what example is this?
This is an example of an endothermic chemical reaction, where energy is absorbed from the surroundings in the form of heat, causing the pack to become cold. The reaction between the chemicals in the instant cold pack and water absorbs heat from the environment, resulting in the cooling effect.
What is in the outer bag of the instant cold pack?
Ammonium Nitrate and water. Urea + plus a Non-Toxic Cooling Additive and Water providing a safer alternative to the dangerous Ammonium Nitrate *Ammonium Nitrate is highly dangerous and used as an oxidizing agent in explosives.
What are 'cold pack' and 'hot pack'?
cold pack contains cold stuff like ice, hot pack stuuf like fire
How does an instant pack work?
An instant pack typically contains a combination of reactive substances that, when exposed to moisture or air, initiate a chemical reaction that produces heat or cools down rapidly. For example, in instant cold packs, ammonium nitrate or urea absorbs water and dissolves, leading to an endothermic reaction that cools the pack. Conversely, instant heat packs often contain substances like calcium chloride that release heat through an exothermic reaction when activated. These packs are commonly used for first aid or therapeutic purposes, providing immediate temperature changes for pain relief or injury treatment.
How does breaking cold pack release cold?

Breaking the pack allows for the substances to mix and react, resulting in the release of cold temperatures.
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.
