参考答案:
Steam at 100 $^{\circ} $ C contains more thermal energy than
water at 100 $^{\circ} $ C. The difference is due to the latent heat of
vaporization, which for water is quite high.
As the steam touches the skin and condenses, a large amount of energy is
released, causing more severe burns. And
the condensed water is still at 100oC , and so more burning can
occur as that water cools.
