WHY is mercury a liquid? The other metals we're used to seeing as solids have a much higher
melting point than mercury.
Mercury, on the other hand, has a melting point of
-38.83°C, so we see it as liquid. If the temperature is lowered to
-39°C, mercury becomes solid, like all metals.
Being in this aggregate state, mercury
begins to evaporate at room temperature, just like any liquid.
