It’s kinetic energy, temperature itself is not a real thing, you are dealing with the bonds that keep water molecules together, if you wiggle hard enought, with enough energy (so… fast enough?) you break free.
I guess another way to look at it is the cloud of elecrons getting more and more messy, so that it destabilizes the bonds…
Wait it’s all models? Always has been.
