Question

What produces more severe burns,boiling water or steam?

Answer 1

Steam produces more severe burns then boiling water.

When water changes into steam at its boiling point it absorbs latent heat of vaporization.
The latent heat of vaporization is 22.5 × 10^5 joules/kg.
This means that steam at 100°C contains much more heat (in the form of latent heat ) than boiling water at the same temperature of 100°C , so when steam falls on our skin and condenses to form water it gives out 22.5 × 10^5 joules/kg of more heat than boiling water at the same temperature.

Since steam gives out much more heat than boiling water it causes more severe burns..

Answer 2

"Steam will produce more severe burns than boiling water.

Like other substances, water can also exist in three physical states,i.e., ice, water, and vapor or steam. As we increase temperature, it shows change in its state from ice to water to steam. It is called as interconversion of physical states.

So, we can state that when we heat water it boils and changes to vapor or steam. This is why steam will cause more worser burns when compared to the boiling water because steam has higher heat energy compare to water because of its latent heat of vaporization."
