Steam. Liquids turn to solids when they reach a temperature, so steam has to be hotter than boiling water.
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 when in contact with human skin steam condenses into boiling water. This causes the serious damages seen in steam burns.
I depends on the heat of the steam, if the steam is hotter than 212 F it will cause more burns because it will circulate around it the air and have access to exposed areas, whereas water will burn only what is in it. The reason I say hotter than 212 F is because while steam circulates it becomes diluted with the air around it which is probably 80 F, and as heat is exchanged between the steam and air it cools, that and as a gas it has many gaps in between molecules meaning fewer will come in contact with and object than it water can in contact with the object. So hot steam will cause more burns on a person than water, but they might be less severe.
Technically speaking steam has a higher temperature, but boiling water often has more heat energy per volume. Steam starts at 100degrees C, which is the absolute maximum temperature of boiling water, but steam can be much much hotter, all the way up to thousands of degrees. However, steam as a gas is much less dense than water, and so steam at 100C will injure a person much less than water at 100C.
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
Hot water has a maximum temperature of 100 degrees centigrade. If it goes beyond that it is now steam. Steam burns are more dangerous because they are much hotter than water.

it boils If you mean "one-hundred degrees Celsius (degrees C)," then that is water's boiling point. What this means is that this is the maximum temperature water can be before it turns to steam. Steam can be much hotter than water because of this, making steam burns more serious than water burns.
Steam has enough kinetic energy to leave the liquid water that is boiling, so it's greater amount of energy results in more severe burns than boiling water, which has a lower amount of energy.
So, steam must lose its heat of vaporization. Think about how it would lose it. Where would all that energy go? It condenses by inputting all the potential energy it has by being a gas into the skin of the person who touches it. Therefore even though steam only has slightly more kinetic energy than almost boiling water, it has a lot more total energy.
I depends on the heat of the steam, if the steam is hotter than 212 F it will cause more burns because it will circulate around it the air and have access to exposed areas, whereas water will burn only what is in it.

Because steam includes the latent heat of vapourisation. As a result, the energy in a kilogram of steam at 100 deg C is 2257 kJoules more than that in a kilogram of water at 100 deg C.
Steam has more heat capacity than boiling water by its condensing to liquid and after that it'll conduct heat better as being liquified.Added: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 liquefied it behaves the same as boiling water: still 100 oC and cooling down is slower than condensation.
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.
