Cold packs have a very practical use in everyday life, if an individual gets injured in some way,
often times their go to is some type of cold pack to use in order to rehab the injury. Conversely, but not
included in this report, heat packs can be used for warmth in times of cold. The point of this report is to
exemplify how to create a cold pack with the given materials, NaOH and H2O.
When mixing NaOH and H2O, the process is very exothermic. This means that the reaction
releases heat, or gets colder. This would be quite effective in creating an item such as a cold pack to treat
injury. Some type of enclosed container or material to hold the compounds separate is ideal, and when the
desired time for the cold pack comes, the materials would be combined and then the desired temperature
achieved. Proper amounts of materials would have to be used in order to achieve the desired temperature,
