Explanation:
When the red-hot metal is placed into the boiling water, it transfers thermal energy to the water, increasing the rate of vaporization.
The boiling point of the water does not change (it remains constant at 100°C at standard pressure), but the extra heat from the metal causes more water molecules to gain enough energy to escape into the vapor phase, thereby increasing the rate of vaporization.
