The core dynamics would be far too complex to be simply decided by temperature alone, but I agree, it would certainly be a big factor in the game. Volcanic activity would probably be a magnitude of dozens more violent and frequent than what we have on Earth. | |

Would the pressure be enough to contain the boiling? What would happen when an eruption occurred and the mercury escaped from the core? Would life be able to sustain itself with an atmosphere completely saturated with mercury vapor? Iron itself boils at 2,862°C and nickel at 2,913°C. It's easily conceived how our core does not boil with the amount of pressure which is on it. | |

Rewrite second paragraph, per invitation after discussion in comments. Note that this is the opposite conclusion!
