In the heating of ice from −20 °C to steam at 120 °C, which segment of the curve is longest?
A.Vaporization plateau
B.Melting plateau
C.Warming liquid water
D.Warming the ice
Explanation
Core Concept
Vaporization (40.7 kJ/mol) dwarfs melting (6.01 kJ/mol) and the modest heating slopes, so the 100 °C plateau stretches farthest along the energy axis.
Correct Answer
AVaporization plateau
