Introduction Hot and cold packs are used by athletes daily in the industry. A soccer player might twist his ankle, as a result his joint might swell up from the excruciating pain. This enlargement of the body part is primarily due to because due to fluid accumulation in the inflicted area, either in the joints (effusion) or in the tissue (edema). To prevent swelling after a muscle or a joint sprain, a hot or cold pack is applied directly onto the skin of the injured body part. A cold pack has two components, a bag containing water and a bag containing a heat-absorbing salt. You can break the bag of water by squeezing on the pack, and the now the water can dissolve the salt contained in the pack. In a cold pack, this reaction of water and the salt is an endothermic reaction, as the heat from the surroundings is taken into the system and lowers the overall temperature of the pack to the point where it feels ice cold, thus the name ice pack.

Cold packs can slows the flow of blood to the inflicted area and prevent further pain and swelling. A hot pack works in the same way and has the same components with one…show more content…
When the liquid dissolves the salt contained with the pack, instead of the system absorbing the heat, the heat from the system is transmitted out into the surroundings, raising the overall temperature of the pack , this is an
