Why burns from steam are more serious than those from boling water?

Text Solution

Verified by Experts

i. Though steam and boiling water have same temperature, the heat contained in steam is more than that in boiling water.
ii. Steam is formed when boiling water absorbs specific latent heat of vaporisation 1.e., `540" cal/g"` .
iii. As a result, when steam comes in contact with the skin of a person, it gives off additional 540 calories per gram causing severe (more serious) bums.
Hence, bums caused from steam are more serious than those caused from boiling water at same temperature.
