The vertical axis is labeled, temperature (degrees C), and ranges from a point below 0 to 100 degrees C. The horizontal axis is labeled, time of heating. The graph shows a line that starts from the origin and slopes upward as the ice heats up until 0 degrees C. The line becomes parallel to the horizontal axis for some time as the ice melts and gets converted to water. The line starts sloping upward again as the water heats up to 100 degrees C. The line again becomes parallel to the horizontal axis as the water boils into steam.

1 answer
The correct option is:
The particles will have the same average kinetic energy and the same temperature during boiling.
During the boiling process, the temperature remains constant as the liquid transitions to gas, even though energy is being added. This means that while the energy is being used for the phase change, the average kinetic energy of the particles (and thus the temperature) remains the same until all the liquid has turned into gas.
