In medicine, a burn is any extremity experienced by the skin caused by heat, cold, electricity, chemicals, friction or radiation (e.g. a sunburn).
Third degree burns
Scalding is a specific type of burning that is caused by hot fluids or gasses. Examples of common liquids that cause scalds are water and cooking oil. Steam is a common gas that causes scalds. The injury is usually regional and usually does not cause death. More damage can be caused if hot liquids enter an orifice. However, deaths have occurred in more unusual circumstances, such as when people have accidentally broken a steam pipe. Young children, with their delicate skin, can suffer a serious burn in a much shorter time of exposure than the average adult. Also, their small body surface area means even a small amount of hot/burning liquid can cause severe burns over a large area of the body.

A cold burn (see frostbite) is a kind of burn which arises when the skin is in contact with a low-temperature body. They can be caused by prolonged contact with moderately cold bodies (snow for instance) or brief contact with very cold bodies such as dry ice, liquid helium, liquid nitrogen, or canned air, all of which can be used in the process of wart removal. In such a case, the heat transfers from the skin and organs to the external cold body (as opposed to most other situations where the body causing the burn is hotter, and transfers the heat into the skin and organs). The effects are very similar to a "regular" burn. The remedy is also the same as for any burn: for a small wound keep the injured organ under a flow of comfortably temperatured water; the heat will then transfer slowly from the water to the organs and help the wound. Further treatment or treatments of a more extended wound also are usual.
