Is cold pack exothermic or endothermic?
Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.
Is the process feeling cold exothermic or endothermic?
Exothermic/endothermic is a process not a feeling.
Is the reaction inside a chemical heat pack endothermic?
The reaction is exothermic.
When a chemical cold pack is activated it becomes cool to the touch what is happening terms of energy?
C An endothermic reaction is occurring, transforming chemical potential energy into thermal kinetic energy.
Is ammonium endo or exothermic?
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
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.
Is a cold pack a exothermic or endothermic?
Exothermic
Is cold a pack a endothermic or exothermic?
Exothermic

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
What type of reaction is occurring when you activate an instant cold pack?
endothermic because the energy is absorbed
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.
Why does a cold pack get cold when the chemical reacts?
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.
Which of the following is endothermic a dry ice evaporating b a sparkler burning c the reaction that occurs in a chemical cold pack often used to ice athletic injuries?
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
What is a endopthermic reaction?
An endothermic reaction is a reaction where heat flows from the surroundings in to the system. Holding an cold pack to your skin is an endothermic reaction; heat flows from your skin (surroundings) into to the cold pack (system).
What is in a cold pack?
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.
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.
