Why steam causes severe burn than whater at same temperature???

Dear student,
 

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.

The energy required in calories to completely convert one gram of water to steam without increasing the temperature is called the latent heat of vaporization. It is called latent heat because it does not increase the temperature. Latent heat of fusion of ice is the heat energy required in calories by one gram of ice to completely convert itself into the water without an increase in temperature.

Regards
