The correct response is:
**The particles will have the same average kinetic energy and the same temperature during boiling.**
During boiling, the temperature of the liquid remains constant; thus, the average kinetic energy of the particles does not change even though some particles are transitioning from the liquid phase to the gas phase.

The correct response is:
**These show where changes of state are occurring.**
In a heating/cooling curve graph, the flat portions represent the phase changes (such as melting or boiling), where the temperature remains constant as the substance transitions between states of matter, despite the continued input of heat.
