Design a portable, 1-time-use hot pack or cold pack for treating injuries. The pack must have 100 g of water separated from a solid chemical and be activated only when the user does something to the pack to mix the 2 components. Your job is to determine how many grams of the chemical are required to achieve the following temperatures: hot pack, 55° C (131° F); cold pack, 3° C (37° F).
What are the measurements I can use to obtain 55° C (131° F) for the hot pack, and 3° C (37° F) for the cold pack? What chemicals should I use for each?
