Howling:"Molten Ice?"

OK, I might not be a professional chemist/physicist, but the "molten ice" in Planet of the Daleks seems... sketchy, to say the least, if we're supposed to believe that it's a variation on the traditional, H2O-based ice. After all, a "molten" variation of that ice is already common on Earth - we call it WATER. So, in order for the story to make a lick of sense, are we supposed to assume that the "molten ice" on Spiridon is another type of chemical that is liquid at sub-zero temperatures, like liquid nitrogen, or is it just a new state of matter that water can take that is currently unknown to modern science?
