Exothermic
What else can I help you with?
Is cold a pack a endothermic or exothermic?
Exothermic
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 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.
If it get cold exothermic or endothermic?
Exothermic phenomenon
Is the process feeling cold exothermic or endothermic?
Exothermic/endothermic is a process not a feeling.
Is a hand warmer pack an endothermic reaction?
Exothermic. It release heat in the process.
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.
Is the reaction inside a chemical heat pack endothermic?
The reaction is exothermic.
Is a cold pack an endothermic reazction?
The reaction is endothermic.
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
Is a chemical packet in a first aid kit endothermic or exothermic?
It would be endothermic. It is endothermic because it is cold and absorbs 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.
