If you double the kinetic energy of ice, does it go from a solid to liquid, solid to gas, or solid to a solid? And how can you tell?


This would depend entirely on what the kinetic energy of the ice was to begin with. If you double 1 you get 2, but if you double 1000, you get 2000 - big difference there.

Whether solid water changes to gaseous or liquid water, or remain solid, depends on what the initial temperature and pressure are. Look up a "phase diagram" - here's one from wikipedia: Phase-diag2.svg Note that if you are in the solid phase (left side of the graph) and change the temperature (assuming this is the effect of "doubling the kinetic energy") then you could end up in the gaseous phase (bottom right) the liquid phase (top right) or remain in the solid phase if the temperature was low enough to begin with.
