To accurately determine which section of the graph represents the liquid state of water, we need to understand the typical phase transition graph for water. This graph usually includes:

  • A temperature axis (x-axis) and an energy axis (y-axis).
  • Areas representing solid, liquid, and gas states of water.
  • Flat sections indicating phase changes (melting and boiling) where temperature remains constant while energy is added or removed.

Typically:

  • A section where the temperature is increasing with energy input without any flat (phase change) lines indicates the liquid state of water.
  • The section below the melting point (flat part at the bottom) represents solid ice.
  • The flat section at the top represents the gas phase (steam) after the boiling point is reached.

If sections B and C are labeled, we can more likely identify Section B or C as the liquid state depending on their respective positions in relation to the water's phase changes.

Without a visual of the graph, I would interpret the liquid state to be typically the section where the temperature increases (assuming it is above 0°C and below 100°C at standard atmospheric pressure). Please double-check the labeled sections for confirmation. If B corresponds to the area between melting and boiling points, then it represents the liquid state of water. If C represents this area, then C would be correct.

If you have specific criteria about the sections themselves (like their positions on the graph or any distinct markers), please provide that for a more tailored response!
