Why does diamond have a higher boiling point than graphite

Whoever told you that diamonds or graphite can melt is pulling your leg. It's true that carbon can exist in liquid form, but that's only possible at very high pressures. And once you allow for arbitrary increase in pressure, you can increase both the melting and boiling point of carbon as high as you like. Under ordinary pressure, carbon

How to Melt Silver (with Pictures) wikiHow

Mar 29, 2019 · If you're melting a large amount of silver, place your foundry crucible on or near your furnace and place the silver inside. Heat the furnace so it's above the melting point of silver, which is 1763°F or 961.8°C. If you're only melting a small amount of silver, place the silver in the foundry and use a blowtorch to melt it.

Element Melting Points Alphabetical and Periodic Table

*Melting Point Notes: 1. At normal atmospheric pressure carbon does not melt when heated, it sublimes. i.e. when heated, carbon undergoes a phase change directly from solid to gas. If the pressure is increased to 10 atmospheres carbon (graphite) is observed to melt at 3550 °C. 2.

What is the differences in physical properties of Diamond

In diamond as well as in graphite carbon atoms are held by strong net work of covalent bonds. Therefore, both have very high melting points. The melting point of graphite is slightly higher than the melting point of diamond because in graphite C___C bonds have partial double bond character and hence are stronger and difficult to break.
