Question

why are the burn caused by steam more painful than burns caused by boiling water​

Answer 1

Answer:

The energy required for water to go from a liquid to a gas is called the heat of vaporization. ... This energy release causes a much worse burn than if the same amount of boiling water were to hit your skin where it would decrease in temperature (to your skins temperature) but would not have to go through a phase change.

Answer 2

Answer:

Steam causes severe burns than boiling water. Particles in steam, that is, water vapour at 373 K (100oC) have more energy than boiling water at the same temperature as particles in steam have absorbed extra energy in the form of latent heat of vaporisation.

the extra energy or the heat in the steam causes more severe burns than boiling water at the same temperature.

hope this  helps...
