Answer 1

Hello
When energy is added to a boiling liquid, the temperature of the liquid does not change. In fact, the added energy is used to break bonds between the liquid molecules and let them escape from the liquid itself, allowing the phase change into a gas. More generally, during a phase change the temperature of the system does not change.
