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.
What happens to the reaction during endothermic and exothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
When cold temperatures are produced in a chemical reaction the reaction is known as?
Endothermic reaction
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.

How cold does and instant cold pack get?
Instant cold packs typically reach temperatures around 32-41 degrees Fahrenheit (0-5 degrees Celsius) when activated. This temperature drop occurs quickly due to a chemical reaction that absorbs heat from the surroundings, making the pack feel cold to the touch.
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.

The reactants have more energy than the products, so energy is released during the reaction.
Is ice hot?
Ice is cold, in the form of water put in a freezer. But some special reactions, such as Instant Ice, emit heat as the supercooling reaction releases energy.
What if yeast does not activate?
Might be old or the water is too cold to activate it or too hot and killed it.
Instant cold packs can be reused?
Instant cold packs cannot be reused once they are activated. The chemical makeup inside the package was created for one time use.
Is does not react with cold water is a physical property?
A reaction with water (hot or cold) is a chemical reaction.
What is the cold can a flame be?
A flame cannot be any cold but always hot even at the first instant it is lit.
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.
Which instant milkpowder dissolve quickly in cold and hot water?
AlpenWeiss
