A student observes that contact with \(1.0\text{ g}\) of steam (\(\text{H}_2\text{O}(g)\)) at \(100^\circ\text{C}\) causes a significantly more severe thermal burn to the skin than contact with \(1.0\text{ g}\) of boiling water (\(\text{H}_2\text{O}(l)\)) at \(100^\circ\text{C}\). Which of the following statements best explains why more thermal energy is transferred to the skin from the steam than from the liquid water?
