Worked Solution
Step 1: Pure water boils at 100°C at sea level.
Step [2-9]: During boiling, heat gain is used to change the state from liquid to gas rather than increasing temperature.
Step [2-9]: Thus, the temperature stays constant at the boiling point.
Correct answer: The temperature will remain at 100°C.
