SUMMARY
Steam burns at 100 degrees Celsius cause more severe skin damage than water burns at the same temperature due to the higher specific enthalpy of steam. While 100-degree Celsius water transfers approximately 200 J of energy to the skin, 100-degree Celsius steam delivers 2254 J, resulting in significant vaporization of water in skin cells. The difference in energy transfer is primarily attributed to the latent heat of steam and the efficiency of heat transfer mechanisms, such as convection, which are more effective with condensing steam compared to still water.
