The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...
Scalding is a type of thermal burn caused by boiling water and steam, commonly suffered by children. Scalds are commonly caused by accidental spilling of hot liquids, having water temperature too high for baths and showers, steam from boiling water or heated food, or getting splattered by hot cooking oil.

A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ionizing radiation (such as sunburn, caused by ultraviolet radiation). [ 5 ] [ 9 ] Most burns are due to heat from hot liquids (called scalding ), solids, or fire. [ 10 ]
However, it is necessary to keep warm water at a temperature of 55–60 °C (131–140 °F) to inhibit the growth of legionella bacteria. The American Burn Association states that a scalding injury occurs when skin is placed in contact with water measuring 155 degrees Fahrenheit, or 68 degrees Celsius, for one second.
A kitchen oven, at a temperature about double room temperature on the absolute temperature scale (600 K vs. 300 K) radiates 16 times as much power per unit area. An object at the temperature of the filament in an incandescent light bulb —roughly 3000 K, or 10 times room temperature—radiates 10,000 times as much energy per unit area.
Giant hogweed sap can make skin extremely sensitive to the sun, causing third-degree burns in a short period of time. This can blind people if it gets in an eye. If you encounter the plant, don't ...
