Experiment 8 Dystan Medical Supply Company inhuman Packs and juicy Packs IN CHEM S125 1705 EXP CHEMISTRY I HONORS Introduction calefactive and unwarmed packs argon used to treat injuries in the hospital to minor injuries at home. For example, snappy packs are used to write a tolerants body temperature down when they arrest deathly wild or to decrease inflammation in a sprained ankle. Hot packs can be used to curb 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 shop cold and gamey packs in large quantities. These packs are make by adjournment table salts in pee. When an ionic fuse dissociates in irrigate it each absorbs muscle from the water or releases energy to the water. When the compound absorbs energy, it does so through erupt energy. This is an heat-absorbi ng 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 all absorbing or emitting heat.

The gist of heat depends on the salts concentration in the water.1 In chemistry, calorimeters are constructed to run across the enthalpy of reactants and calculate the heat evolved. At constant impel the enthalpy is the heat gained or lost by a system . A calorimeter is a gimmick that is a clo! sed system. Therefore, no energy can see the system, so any salmagundi 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 must first be calibrated by having a know amount of substance at a known...
