Answer:

The part of the heating curve that corresponds with the boiling of liquid water is represented by option C.

Boiling is the process in which a liquid changes into its gaseous state by the formation of bubbles within the liquid. It occurs when the vapor pressure of the liquid equals or exceeds the atmospheric pressure. In the case of water, this happens at 100 degrees Celsius (or 212 degrees Fahrenheit) at standard atmospheric pressure.

In the given heating curve, we can see that the temperature initially rises from -50°C to 0°C, which represents the solid phase of water (ice) being heated. This is followed by a plateau where the temperature remains constant at 0°C, indicating the phase change from solid to liquid as ice melts. Once all the ice has melted, further heating causes the temperature to rise again until it reaches 100°C. This portion of the curve corresponds to heating liquid water.

Option C on the graph shows a temperature range between 0°C and 100°C, which aligns with the boiling point of water. Therefore, option C represents the part of the heating curve that corresponds with the boiling of liquid water.
