Endothermic phase changes
« on: December 11, 2007, 09:33:44 PM »
17)   Which of the following phase changes is endothermic?
A. condensation (g > l)
B. solidification (l > s)
C. vaporization (l > g)
D. deposition (g > s)
E. melting (s > l)

The answer is E but wouldn't vaporization be endothermic as well??
