Question

which of the following causes more severe burn: steam or water. Why ?

Answer 1

steam causes more severe burns at the same temperature because it has latent heat of vaporization so it has more kinetic energy than water.

Answer 2

Answer:

Steam causes more severe burn than boiling water.

Boiling water at 100°C changes into steam at 100°C absorbing latent heat of vaporisation. Due to this extra amount of heat steam causes more severe burns than boiling water although the two are at the same temperature.
