Answer:
Horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases.
Step-by-step explanation:
The temperature is constant during a phase change (melting or boiling), so the graph is a horizontal line.
The temperature increases when a single phase (solid, liquid, or gas) is heated, so the graph for these changes has an upward slope.
A is <em>wrong</em>. A horizontal line shows a constant temperature.
B is <em>wrong</em>. There are no vertical lines in a heating curve.
D is <em>wrong.</em> A horizontal line does correspond to an increase in temperature.
