Can boiling water go over 100 degrees?

Liquid water generally doesn’t go higher than 100 degrees Celsius, as that is its boiling point (under standard conditions). At this point it undergoes a phase change into steam, which is still water, but in the gas phase. Steam can (and does) get hotter than 100 degrees Celsius, and can be very dangerous as a result.

Do all kettles boil to the same temperature?

Answer: Kettles do not heat water uniformly. Put simply, kettles heat water at different temperatures in different places. Water around the heating element will be far hotter than water near the surface. You are therefore seeing some of the water boiling, but not all of it.
