Question
Why does steam cause more severe burns than boiling water?
✓

Answer

Steam causes more severe burns than boiling water because the steam contains more heat, in the form of latent heat, than boiling water. Hence, when steam falls on our skin and condenses to produce water, it gives out 22.5 × 105 Joules per kilogram more heat than boiling water.
