Answer

Brief Explanations:

Heating curves show phase - change and temperature - change processes. Starting from the bottom left, the first flat section is melting (solid to liquid), then the sloped section is the liquid state being heated. The next flat section is vaporizing (liquid to gas), and the final sloped section is the gas state being heated. The lower left region is solid, the middle region is liquid, and the upper right region is gas.

Answer:

From bottom - left flat section: melting Bottom - left sloped region: solid Middle sloped region: liquid Middle flat section: vaporizing Upper - right sloped region: gas
