High melting and boiling points
WebHigh Melting and Boiling Points As a result of powerful metallic bonding, the attractive force between the metal atoms is quite strong. In order to overcome this force of attraction, a great deal of energy is required. This is the reason … WebThe more energy that is needed, the higher the melting point or boiling point. Explanation There are intermolecular forces between simple molecules. Intermolecular forces are much weaker...

Silicon has a very high melting point due to its giant covalent structure; a lot of energy is needed ... オタク うちわ 文字 作り方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 ... parallel slope propertyWebmelting and boiling points increase with: increasing atomic/molecular size why do larger atoms have a higher melting and boiling point? In a larger atom, the valence electrons are, on average, farther from the nuclei than in a smaller atom. Thus, they are less tightly held and can more easily form the temporary dipoles that produce the attraction. parallels nvidia driversWebFinal answer. 1.
