Why do covalent bonds have low melting and boiling points Class 10? Covalent compounds have weak forces of attraction between the binding molecules. Thus less energy is required to break the force of bonding. Therefore covalent compounds have low melting and boiling point. Is LiF a covalent compound? Ionic vs Covalent Bonding Ionic bondingThe formation […]

Which length of wire offers the greatest resistance?
Which length of wire offers the greatest resistance? The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. The relationship between resistance and wire length is proportional . Can I replace 40W incandescent with 60W LED? When it comes to […]
