Question

Why more serious burns are caused by steam at 1000c than water at same temperature?

Answer 1

Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat of vaporisation. Steam and boiling water can exist at varying temperatures but it is only correct to assume here that both are at the same temperature.

Answer 2

More serious burns are caused by steam at 1000c than water at same temperature

Explanation:

• Steam comprises more heat in the latent heat of vapourisation form. Steam has more energy at 1000cc when compared with boiling water at 1000cc. When it condenses with liquids on the skin, the steam releases tremendous energy.
• Therefore, when steam falls on skin and condenses to generate water, it gives out 22.5x105J/kg more heat at 1000cc than boiling water at 1000cc, that is, the same temperature. Thus, burns produced by steam at 1000cc are far more severe than burns produced at 1000 cc by boiling water.
