Steam causes more severe burns as compared to boiling water because steam contains more heat (i.e
40.6 kJ
/mol
condensation heat) then boiling water, both at the same temperature 100 oC.
From that condensation is momentanous
when in contact with skin, after being liquidified
it behaves the same as boiling water: still 100 oC and cooling down is slower than condensation.
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.
steam is the gaseous transformation that takes place on heating water to its boiling point.Steam will give you more burn than the water boiling at 100 c as it has the latent heat of vapourisation in addition to the heat of fusion.Basically it has more heat content in the steam state than boiling water state.
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.
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.
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 steam burn is generally more severe than a water burn because steam carries more heat energy than water due to its high temperature. Steam can cause more damage to the skin upon contact and penetrate deeper into the tissue, resulting in a more serious burn.

steam causes severe burns because of change of state i.e. liquid to gas with effects our skin. where as boiling water is only liquid which is hot but it does not effect the skin more than water.Thus higher the temperature of steam as compared to water. cause more severe burns than boiling water
Steam can cause more severe burns than boiling water because it carries additional energy in the form of latent heat. When steam comes into contact with skin, it condenses into water, releasing this extra energy and resulting in a more intense burn. In contrast, boiling water can cause burns as well, but it lacks the same energy transfer that steam provides. Therefore, steam is generally considered more dangerous in terms of burn potential.
A scald from steam at 100°C hurts more than water at the same temperature because steam contains additional energy in the form of latent heat. When steam condenses on the skin, it releases this extra energy, resulting in a more severe burn. Additionally, steam can penetrate the skin more effectively than water, leading to deeper tissue damage and increased pain. This combination of factors makes steam burns more intense and painful than burns from boiling water.
More serious burns are caused by steam at 100°C than water at the same temperature due to the latent heat of vaporization. When steam condenses on the skin, it releases a significant amount of heat energy, resulting in a more severe burn. Additionally, steam can penetrate the skin more effectively than water, causing deeper tissue damage. Thus, the combination of higher heat transfer and penetration makes steam more dangerous than water at the same temperature.
Steam burns are painful because they damage the skin just like any other burn. Steam burns hurt because the water in steam keeps the heat trapped in the skin.
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.
In theorie... no... in practice... yes. The steam has 6 times the amount of heat energy. If the 1 gram of steam would be applied to the same surface area of skin as the 1 gram of water, and all the steam would give off its heat till it has the same temperature of the skin, it would have given off about 6 times the amount of heat as the liquid water. This would result in a way more severe burn. But steam wil spread its heat over a way larger surface area, it wont condens easily on your skin (because a skin temperature of 30oC isn't exactly cold) and it doesnt stick to your skin like liquid water does. So i would rather have the 1 gram of steam poured over me than the 1 gram of water.
Steam at 100 degrees Celsius contains more heat energy compared to liquid water at the same temperature. When steam comes into contact with skin, it releases this extra heat quickly, causing more severe burns compared to liquid water of the same temperature.
