Answer 1

Answer:

Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.

Answer 2

Answer:

Steam has more energy than boiling water. It possesses the additional latent heat of vaporization. So, when steam falls on skin and condenses to produce water it gives out 22.5 x 10^5 J/kg more heat than boiling water at the same temperature. Therefore, burns produced by steam are more severe than those produced by boiling water. Steam has more energy than boiling water. Therefore, burns produced by steam are more severe than those produced by boiling water.
