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.
What else can I help you with?
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.
How fluorine reacts with cold water?
fluorine reacts with water veryviciously the chemical equation for it is fluorine + oxygen = fluorine oxide
Example how a cold pack works?
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.
Is it a physical property or chemical property if it reacts with a base to form water?
It is a chemical property. When a substance reacts with a base to form water, it undergoes a chemical change, illustrating its chemical reactivity.

an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
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.

What chemical in baking soda reacts to vinegar?
The chemical that reacts with vinegar is sodium bicarbonate.
Which compound could you use to make a cold pack?
You can use ammonium nitrate to make a cold pack. When the salt dissolves in water, it absorbs heat from its surroundings, causing the pack to become cold.
