Question
Explain why:
Burns caused by steam are more severe than burns caused by boiling water.

Answer

Burns caused by steam are more severe than burns caused by boiling water because of high specific latent heat of condensation. 2268 J/g of heat is released when 1 g of steam condenses to form 1 gm of water.
Due to the high specific latent heat of solidification of water, rivers and lakes do not freeze easily.
