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 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.
No, increasing the boiling point of water with additives does not increase the temperature of the vapor or steam produced. The temperature of the vapor or steam will remain the same as it is determined by the boiling point of water, regardless of any additives.
No, salt does not affect the temperature of steam. Adding salt to water increases the boiling point of the water, but once the water has turned into steam, the temperature of the steam remains the same.
Superheated steam is steam at a temperature higher than water's boiling point
stream will produce more severe burns than waterAdded: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 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.
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.

Boiling is the temperature at which a substance changes from a liquid to a gas. It is not necessarily the maximum temperature a substance can reach, as some substances can be heated to higher temperatures without boiling.
No, salt does not affect the temperature of steam. Adding salt to water increases the boiling point of the water, but once the water has turned into steam, the temperature of the steam remains the same.
373.15 K = 100°C = 212°F = boiling point of water at sea level Steam at that temperature causes severe burns because it is very hot, and because water is very efficient at transferring heat. The steam also has a significantly greater amount of heat than liquid water just below the boiling point, because the steam also has the latent heat of vaporization.
Superheated steam is steam at a temperature higher than water's boiling point
The temperature at which water turns into steam is called the boiling point, which is 100 degrees Celsius (212 degrees Fahrenheit) at sea level.
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.
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.
Steam is more dangerous because the temperature is higher.
