Which of the following correctly indicates the relationship between the regions of the graph and the corresponding phases:
A) 1: solid, 2: phase change from solid to liquid, 5: gas
B) 2: solid, 3: phase change from solid to liquid, 4: liquid
C) 1: phase change from solid to liquid, 4: gas
D) 1: solid, 2: phase change from liquid to gas, 3: liquid
The diagram shows the relationship between heat added to a substance and its temperature. It shows that during phase changes there is no change in the temperature. The regions noted are:
2: phase change from solid to liquid (melting / fusion)
4: phase change from liquid to gas (boiling / vaporization)
Only choice (A) correctly indicates these regions.
