Thermal Energy Quick Check 4 of 44 of 4 Items 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 is the best interpretation of the two flat portions of the graph? (1 point) These show where thermal energy does not exist. These show where thermal energy does not exist. These show where changes of state are occurring. These show where changes of state are occurring. These show where kinetic energy is increasing. These show where kinetic energy is increasing. These show where temperature is 0ºC.
