Question

which one produces more severe burns, steam or boiling water? Explain.

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 vaporization.

Answer 2

Answer:

• When water changes into steam at its boiling point, it absorbs latent heat of vaporisation (which is 22.5 x 109 joules per kilogram).
• 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 x 105 joules per kilogram 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.
