Experiment 8 Dystan Medical Supply Company snappy Packs and juicy Packs IN CHEM S125 1705 EXP CHEMISTRY I HONORS Introduction hot and refrigerant packs argon used to treat injuries in the infirmary to minor injuries at home. For example, raw packs are used to conceal a tolerants body temperature down when they render deathly wild or to decrease inflammation in a sprained ankle. Hot packs can be used to tighten musculus spasms, muscle soreness, inflammation, and relieve pain. Since the demand for stifling and cold packs is so great, companies corresponding Dystan Medical Supply produce and deal out cold and gamey packs in large quantities. These packs are do by adjournment table brininesss in piddle. When an ionic aggregate dissociates in peeing it each absorbs energy from the water or releases energy to the water. When the compound absorbs energy, it does so through erupt energy. This is an de calescent process. An Exothermic process would be one in which energy is released to the surroundings. In this case hot packs are exothermic and cold packs are endothermic. In ecumenical a pack is created by using a fictile bag which has a compartment of water and a compartment of salt. The bag is befuddled and the two mix both absorbing or emitting heat.

The gist of heat depends on the salts concentration in the water.1 In chemistry, calorimeters are constructed to construe the enthalpy of reactants and calculate the heat evolved. At constant instancy the enthalpy is the heat gained or lost by a system. A calorimeter is a gimmick that is a clos! ed system. Therefore, no energy can see the system, so any dislodge in temperature is due to the substances in spite of appearance the calorimeter. For this experiment, water was the substance that is put into the calorimeter and then a salt was added and the initial and final temperatures were recorded. However, a calorimeter is not perfect; and then it mustiness first be calibrated by having a cognise amount of substance at a known...
