请看Form 4 Chemistry Textbook page 14 Figure 2.4。将melting、freezing、condensation、evaporation、boiling 和 sublimation 的意思背在脑海里。

请看Form 4 Chemistry Textbook page 15 Figure 2.6
B, C = melting point
D = boiling point
AB = solid state
BC = solid and liquid state
CD = liquid state

请看Form 4 Chemistry Textbook page 15 Figure 2.7
F, G = freezing point
EF = liquid state
FG = liquid and solid state
GH = solid state

把以上的背进脑海里，并且想办法理解，因为它们是SPM的问题，100%出的。
