Which gives the more sever burn, water or steam both at 100C? I think it is the steam because it has more kinetic energy in it, as the water molecules have broken the bonds of the liquid and has a lower specific heat capacity, but I would like some confirmation, or if incorrect the right answer and why.
Thanks in advance to the person/s who reply

Yes, steam at 100 degrees would cause the more severe burn owing to the fact that for water to be converted into heat, energy is required (known as latent heat of vapourisation), which in turn increases the KE of steam molecules .

Water vs Steam burn


hi,
specific volume of vapour at super-heated condition is less than at saturated vapour condition, hence, super-heated steam is easily transferable(higher KE), that is why, these are applied in boilers as they are carried at a faster rate & the energy carried by each vapour part is higher enough to cause turbine operation at a lower mass flow rate due to its high KE..
