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.
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.
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.
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.
Steam can cause more severe burns than boiling water because steam has a higher heat energy content. When steam comes into contact with the skin, it releases this heat energy, causing more damage than boiling water at the same temperature.
steam is more effective because the particles of steam have absorbed extra energy in the form of latent heat of vaporization apparent temp is 100c and actual temp is more than 100c whereas the actual temp of water is 100c
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.

Greater latent heat in steam due to phase change.
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.
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
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.
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 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.
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.
