Question

What is metal ? How we melt diamond

Answer 1

Explanation:

Liquid carbon is like hydrogen being compressed into a high density metallic lattice, so carbon takes a metallic form under these conditions. You can see clearly that unless it is done in a pressure anvil, heating of diamond will not melt it, instead you get graphitisation.

WHAT IS A METAL?

• A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well.

HOW CAN WE MELT DIAMOND?

• Using super-strong magnetic fields, scientists fired small plates at 34 kilometres per second towards tiny pieces of the mineral, subjecting them to 10 million times normal atmospheric pressure.
• The diamond melted then re solidified.
