endothermic because the energy is absorbed
You can find "Instant Fusion" in Cyberdark Impact and Champion Pack Game 7.
It's literally a pack that instantly cools by either shaking, or breaking the packet that's inside the outer packet, and mixing the ingredients together. It then, INSTANTLY, cools. Same for instant heat packs.
Heat energy is transferred by conduction from the muscle to the cold pack.
To quickly and conveniently provide heat therapy with an instant reusable heat pack, simply activate the pack by bending or clicking a metal disc inside. This will trigger a chemical reaction that generates heat. Place the pack on the desired area for relief. Reuse by boiling the pack in water to reset the chemical reaction.
Instant heat packs work by utilizing a chemical reaction to generate heat quickly. When the pack is activated, the chemicals inside react and produce heat as a byproduct. This heat is then released, providing quick and convenient heat therapy for sore muscles or injuries.

You can find reusable instant heat packs at most drugstores or online retailers. Look for packs that can be reheated multiple times by boiling or microwaving.
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
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.
