Experiment 8 Dystan Medical Supply Company cutting Packs and juicy Packs IN CHEM S125 1705 EXP CHEMISTRY I HONORS Introduction hot and dusty packs argon used to treat injuries in the infirmary to minor injuries at home. For example, rimed packs are used to follow a tolerants body temperature down when they hold out deathly wild or to decrease inflammation in a sprained ankle. Hot packs can be used to wither 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 shit cold and gamey packs in large quantities. These packs are do by adjournment table salinitys in body of water system. When an ionic immix dissociates in water it each absorbs zipper from the water or releases energy to the water. When the compound absorbs energy, it does so through erupt energy. This is an end oergic 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 determine the enthalpy of reactants and calculate the heat evolved. At constant pull the enthalpy is the heat gained or lost by a syst em. A calorimeter is a gimmick that is a c! losed system. Therefore, no energy can see the system, so any motley 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 sign and final temperatures were recorded. However, a calorimeter is not perfect; and then it must(prenominal) first be calibrated by having a know amount of substance at a known...
