Worked Solution
Step 1: Boiling is a process where a liquid changes to a gas at its boiling point (100°C for pure water).
Step [2-9]: During a change of state, heat is gained to break the bonds between particles, so the temperature remains constant.
Step [2-9]: The water continues to gain heat from the burner while staying at 100°C.
Correct answer: The water gains heat and its temperature remains at 100°C.
