Question

Give reason for the following

Steam causes much more severe burns than boiling water at the same temperature.

Answer 1

1. Steam has more energy than boiling water. It possesses the additional latent heat of vaporization.
2. As steam falls on the body and condenses it gives out $22.5\times {10}^{5}J/Kg$ more heat than boiling water at the same temperature.
3. Steam has more energy than boiling water. So, burns produced by steam are more severe.
