How can you harden liquid mercury into a solid?

Answer 1

Add an alloy powder containing silver, tin and copper to it in a 1:1 ratio, and you'll get an "amalgam." This is used by dentists to fill teeth, and it works well. Sticking it in the freezer probably won't work unless you've got a really good one--its melting point is 37 below zero F.

Answer 2

By cooling it. Mecury turns solid at about -40 degrees Celsius.

Answer 3

Mercury is the only liquid metal having high boiling point it is already a non volatile liquid.

Answer 4

You can change Mercury from a liquid to a solid state by taking it to or below -40 degrees. It does not matter if you use a Centigrade thermometer or Fahrenheit one.

Answer 5

Mercury's melting point is -38.83°C, so cooling it below that temperature will cause it to solidify. When mixed as an alloy (amalgam) with silver, it will also remain a solid.

Answer 6

Liquid mercury can be hardened into a solid by cooling it to below its freezing point of -38.83°C (-37.89°F). Once the temperature drops, the mercury will solidify into a hard, brittle mass.

Answer 7

Heat it to 357 degrees Celsius.
