Question
Use the graph and diagram to answer the question.
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.
Which option describes the particles of water as the liquid water actively boils?
