Contact with steam inflicts more severe thermal burns than boiling water due to its higher content of _________________?
Show answer Hide answer
Answer: B. Latent heat of vaporization
Explanation
Steam inflicts severe thermal burns because it releases the large latent heat of vaporization. Condensing steam transfers enormous amounts of thermal energy directly to the skin upon contact. Boiling water at the same temperature lacks this extra stored phase change thermal energy. Latent heat of vaporization is the energy required to transform a liquid into gas at constant temperature. Phase changes involve significant energy absorption or release without changing the system temperature. Skin tissue absorbs both sensible heat and latent heat when exposed to condensing steam.
Industrial steam systems require strict safety insulation to prevent severe accidental burn injuries. Steam sterilization in medical autoclaves utilizes this high thermal energy transfer capability efficiently. Understanding latent heat prevents dangerous handling practices around high pressure steam equipment. Latent heat of fusion relates to the phase change between solid and liquid states of matter. Latent heat of sublimation describes the direct transition between solid and gaseous phases. Selecting all options is incorrect because only vaporization applies to steam condensation burns.
