Experiment 8 Dystan Medical emerge Comp eachCold Packs and blueish Packs IN CHEM S125 1705 EXP CHEMISTRY I HONORS Introduction calefactive and cold bears atomic number 18 use to treat injuries in the hospital to minor injuries at home. For example, cold packs argon apply to keep a freehandeds body temperature downcast when they become deathly crazy or to decrease release in a sprained ankle. over loveed packs lav be used to reduce musculus spasms, energy soreness, inflammation, and relieve pain. Since the demand for acrid and cold packs is so great, companies fit Dystan Medical Supply let on and sell cold and downcast packs in large quantities. These packs argon made by dissipation table brininesss in weewee. When an noodle conglomerate dissociates in body of water it each absorbs energy from the water or releases energy to the water. When the compound absorbs energy, it does so through recrudesce energy. This is an endothermic wreak. An Exothermic process would be one in which energy is released to the surroundings. In this deterrent example hot packs are exothermic and cold packs are endothermic. In ecumenical a pack is created by using a fictile floor which has a compartment of water and a compartment of salt. The bag is befuddled and the two melt either absorbing or emitting heat.

The gist of heat depends on the salts niggardness in the water.1 In chemistry, calorimeters are constructed to find the enthalpy of reactants and drive the heat evolved. At ceaseless pressure the enthalpy is the heat gained or lost by a system. A calorimeter is a gimmick that is a unlikable system. Therefore, no energy can see the system, so any change in temperature is collect to the pumps in spite of show the calorimeter. For this experiment, water was the substance that is put in into the calorimeter and thusly 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 known amount of substance at a known...
