WebMelting and boiling points are affected by the forces between molecules. The larger the attractive forces between the molecules, the more energy needed to overcome them so that molecules can move past each other freely or evaporate (melt or evaporate). WebSubstances with small molecules have low melting and boiling points and do not conduct electricity. Giant covalent substances have very high melting points.

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. 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. ...
