Why molecular substances with weak intermolecular forces have low melting points?
The cause is just this weak intermolecular force, ease to be broken.
How melting and boiling points are affected by intermolecular forces?
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
How does molecule size affect melting point?
Intermolecular forces increase as molecular size increases, thus the bigger the molecular size, the bigger the molecular mass, the stronger the intermolecular forces, the more energy required to break the bonds between the molecule, thus a higher melting/boling point.
Why do dipole forces have an impact on the melting and boiling points of substances?
Dipoles are a form of intermolecular force which holds molecules together. The greater the intermolecular force, usually the greater the boiling point, for example.
Why do oxygen and methane have low melting points?
The melting point of a substance depends, in part, on whether one or more intermolecular forces act to attract the molecules of the substance, and on the strengths of these forces. In the cases of the substances you mention these forces are absent or very small.
Why molecular substances with weak intermolecular forces have low melting points?
The cause is just this weak intermolecular force, ease to be broken.
Does the melting point depend on the substances being melted?
Yes, because the melting point depends on the strength of the intermolecular forces, which are different for different molecules and compounds. Stronger intermolecular forces mean a higher melting point.
Which inter molecular force would cause the highest melting point?
Hydrogen bonding, which is the strongest of the intermolecular forces.
How melting and boiling points are affected by intermolecular forces?
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
How does molecule size affect melting point?
Intermolecular forces increase as molecular size increases, thus the bigger the molecular size, the bigger the molecular mass, the stronger the intermolecular forces, the more energy required to break the bonds between the molecule, thus a higher melting/boling point.
Why do substances made up of simple molecules have low points?
Substances made up of simple molecules have low melting points because there are strong bonds between the atoms in the molecule, but weak bonds holding the molecules together. Therefore, the intermolecular forces break fairly easily, due to the fact that they are weak and the covalent bonds making up the molecule do not break because they are strong. This means that, due to the weak intermolecular forces breaking down easily, simple molecular substances have low melting and boiling points.
How can the boiling and the melting point be used to help identify substances?
intermolecular forces are hard to overcome...apex
How are the melting points of ionic compounds different from molecular compounds?
Very much higher.
What is an Inter molecular force?
Intermolecular forces are any forces exerted on neighboring molecules of a given compound. The forces are not the actual chemical bonds present in the substance, but rather the substances own attractiveness to its own molecules. These intermolecular forces play a crucial role in determining a compounds various physical properties such as but not limited to :solubility, melting point, boiling point, density.
Why do dipole forces have an impact on the melting and boiling points of substances?
Dipoles are a form of intermolecular force which holds molecules together. The greater the intermolecular force, usually the greater the boiling point, for example.

What type of molecular forces of attraction would exist in CaO?
intermolecular forces
