High melting and boiling points

WebA liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100°C (212°F) at sea level, but at 93.4°C (200.1°F) at 1900 metres (6,233 ft) altitude. ... As with boiling points, the melting point of a solid is dependent on the strength of those attractive forces. For ... WebThe highest melting points are found in network covalent solids such as diamond, graphite and silicon dioxide. A giant covalent structure has many strong bonds holding it together. The next highest melting points are found in some metals, notably transitional metals.
