Dystan Medical Supply Companyâ€"Cold Packs and juicy Packs
IN CHEM S125 1705 EXP CHEMISTRY I HONORS
Introduction
calefactive and cold packs argon used to treat injuries in the hospital to minor injuries at home. For example, cold packs are used to keep a tolerants body temperature down when they become deathly wild or to decrease inflammation in a sprained ankle. Hot packs can be used to reduce 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 sell cold and gamey packs in large quantities. These packs are made by adjournment table salts in water. When an ionic compound dissociates in water 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 endothermic 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 either absorbing or emitting heat.
The gist of heat depends on the salts concentration in the water.1
In chemistry, calorimeters are constructed to find the enthalpy of reactants and calculate the heat evolved. At constant pressure the enthalpy is the heat gained or lost by a system. A calorimeter is a gimmick that is a closed system. Therefore, no energy can see the system, so any change 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 known amount of substance at a known...
