Why are steam burns on the skin so severe?
It is not really more. Steam is the gas form of water, and thus hotter than the liquid form. 1000C (at 1au at sea level) is the boiling point of water. 400C water will not burn you, but 990C will. Steam at 1010C will burn you, but steam at 5000C would burn worse. So your answer is steam is hotter, but how much more of a burn you get also has to do with the amount of steam or water you come in contact with, and the temperature the steam or water is.
Why steam burn is more than hot water burn?
Previous answer was "It can be at a higher temperature" that's true but not nearly the whole story. A magicaly property of water-steam is the huge amount of energy involved in the "Latent Heat of Vaporization", that's the energy required to vaporize water to steam after the fluid is at boiling temperature (nominal 212F). To heat water takes about 1 BTU/lb-Deg F so heating water from 112 to 212 takes about 100 BTU, once at 212 F it take another about 1,000 BTU to vaporize it, no change in temperature, still at 212 F. So going the other way, such as with a steam burn your skin must remove that same 1,000 BTU just to condense the steam before the temperature drops at all. So answer is not just the temperature but the huge amount of energy in the steam that holds that temperature. With water, by the time 100 BTU/lb are transferred to your body, water is down to 112 F, if you get hit with steam, your body must absorb 1,100 BTU/lb of steam before you get to that condition. Get it? 11-time more energy so a very much worse burn.
Why does steam burn skin more than hot water?
Steam causes more severe burns as compared to boiling water because steam contains more heat (i.e40.6 kJ/molcondensation heat) then boiling water, both at the same temperature 100 oC.From that condensation is momentanouswhen in contact with skin, after being liquidifiedit behaves the same as boiling water: still 100 oC and cooling down is slower than condensation.
Why is a steam burn worse than a hot water burn?
Because gases or vapours like steam are much poorer conductors than liquid water. The heat energy given to the skin area takes longer to dissipate (or go away), so the damage to your skin is greater.
Why steam causes more severe burns than boiling water?
Boiling water is by definition a temperature of 212 degrees F (100 degrees C), because it is moving through the phase change. Steam is water vapor and already past the phase change from liquid to gas and so can be a much higher temperature. The higher the temperature, the more severe the burn.
A burn or injury to the flesh by hot liquid or stream?
Is called a 'scald'.
What does scalding mean?
To burn with hot liquid or steam, to treat with boiling water, to criticize harshly
What is the meaning of scald?
To burn with hot liquid or steam; to pain or injure by contact with, or immersion in, any hot fluid; as, to scald the hand., To expose to a boiling or violent heat over a fire, or in hot water or other liquor; as, to scald milk or meat., A burn, or injury to the skin or flesh, by some hot liquid, or by steam., Affected with the scab; scabby., Scurvy; paltry; as, scald rhymers., Scurf on the head. See Scall., One of the ancient Scandinavian poets and historiographers; a reciter and singer of heroic poems, eulogies, etc., among the Norsemen; more rarely, a bard of any of the ancient Teutonic tribes.
What does freon do to the skin?
In it`s liquid state it will give you a nasty burn like injury.
How long does it take for human flesh to burn?
Skin is another name for the human flesh. Human flesh is an organ and has cells within it. The human flesh will burn immediately when touched by fire.
Steam is to water as liquid is to?
steam is to liquid as smoke is to fire

Why do we get a more severe burn from steam at 100 Degree Celsius than from an equal amount Of water at the same temperature?
In order to turn from water to steam, the liquid must absorb a large amount of energy. Even though they may be the same temperature, this extra energy means the steam can cause a more severe burn.
Is this burn healing (1 week post burn)?
Burn injuries are caused by fires or flames, hot liquids or steam, contact with a hot object or agent like grease or tar, chemicals, or electricity. When evaluating a burn injury, doctors look at two factors: how deep the burn is and the burn size which is measured by the percent total body surface area (% TBSA). The burn depth depends on how hot the agent was and how long the burned area was in contact with the agent and how thick the skin is in the area. There are three levels of a burn injury:
Can steam burn you?
Yes
Why is a burn caused by a steam more severe than a burn caused by a boiling water if they have the same temperature?
Steam carries more energy than boiling water. When water is at its boiling point, it requires additional energy to boost it into a gaseous state. When the steam comes in contact with a cooler object and condense back to a liquid, it releases that energy as heat. If that object is human skin, that heat will cause a burn. - - - - - It would be very rare to have steam with the same temperature as boiling liquid water. The only way to keep water liquid past 100 degrees C is to put it under pressure. By contrast, once you have formed steam you can raise it to just about any temperature you want - there are many industrial processes that require steam at 600 degrees F. Hence, at least part of the reason burns from steam are more severe than burns from boiling water, is the steam is hotter.
Why when heating most organic volatile liquid's is it a good idea to use steam and not a Bunsen burner?
If you use Bunsen burner, you might burn the volatile liquid. Also, because it is organic, the fire would likely spread to you because it would burn too fast for you to react.
