How To Activate a Heat Pack
What is Heat Pack?
A heating pad is a pad used for warming of parts of the body in order to manage pain. Localized application of heat causes the blood vessels in that area to dilate, enhancing perfusion to the targeted tissue. Types of heating pads include electrical, chemical and hot water bottles.
How To Activate a Heat Pack
To prepare the heat pack for activation, its contents are first heated to a temperature above the melting point of sodium acetate to completely melt it.

What makes a hot pack work?
A hot pack is produced if an exothermic reaction occurs as the salt and water mix and heat energy is released because this process will raise the temperature of the contents in the pack.
Can I boil a hot pack?
The heating pack can be placed in boiling water and the sodium acetate can be dissolved again. This phenomenon shows how bond energy can be released.
How long do heat packs last?
