Ice pack
From Wikipedia, the free encyclopedia
This article is about a sac filled with a coolant. For sea ice, such as Arctic ice packs, see Pack ice
An ice pack (commonly used therapeutically) is a plastic sac of crushed or cubed ice, refrigerant gel or liquid, or even frozen vegetables.
This refrigerant, usually non-toxic, can absorb a lot of heat, since its specific heat is very high.
It is commonly used to alleviate the pain of minor injuries.
The most common use of an ice pack is simply, a sac filled with crushed ice.
