Question

why steam causes severe burn than boiling water

Answer 1

Boiling water contains only a specific amount of heat energy required for it to boil. However, as steam is formed from boiling water, it contains the heat energy of boiling water, along with the latent heat of vaporization. Hence, assteam has more heat energy, it cancause more severe burns than boiling water.


Or

Steam has more energy than boiling water. It possesses the additional latent heat of vaporization. Therefore, burns produced by steam are more severe than those produced by boiling water
