ANSWER
Temperature will remain the same
EXPLANATION
When water reaches it boiling point at 100 degrees Celcius, the molecules of water will start moving independently and collide with each other.
At 100 degrees Celcius, it has attained an equilibrium between the liquid and vapor phase. Therefore, when energy is added to it, the temperature will remain the same and there will be a phase change.
Hence, the temperature will remain the same.
