Viscosity is a measure of resistance of a fluid t flow. When a fluid flows, a portion of it moves with respect to the neighboring portions. Since there are cohesive forces between the molecules of that liquid, like intermolecular forces, these forces create an "internal friction" which reduces the rate of flow of that fluid, so when a substance has greater IMF, these frictional forces are stronger. Therefore, it has more resistance toward moving.

∙ 11y agoThe stonger the intermolecular forces (between molecules), the shorter the distance between those molecules and the denser it is. Think of a solid. It has a high density because it holds its shape and volume. The particles are held together by ionic forces of attraction as opposed to dipole-dipole forces or LDFs. Ionic forces are the strongest type of intermolecular force. Thus, solids which use it, have the highest density. It is an inverse relationship, and density depends on the strength of intermolecular forces.

Is the boiling point higher for compounds with a high viscosity?
Viscosity is the thickness of the compound. The thicker the compound the higher the intermolecular forces. The higher the intermolecular forces the higher the boiling point is.
What does a high melting point temperature indicate about a substance?
Strong Intermolecular Forces attract the molecules
Why is silicon a suitable material for lining furnaces?
Silicon dioxide is suitable for lining furnaces because of its very high melting point of 1,600 to 1,725 degrees celcius. It is so high because of the strong intermolecular forces between SiO2 molecules in the giant covalent structure comparable to that of diamond and graphite. A large amount of energy is required to overcome these intermolecular forces and thus SiO2 has a high melting point. Note: no silicon-oxygen bonds are broken during melting, just intermolecular forces between SiO2 molecules.
Why do compounds with strong intermolecular attractive forces have higher boiling points than compounds with weak intermolecular attractive forces?
Heat is simply an expression of how fast molecules are vibrating and moving about, for the purposes of state of matter. Intermolecular bonds are what stop this motion from happening, so the stronger this bond, the higher the temperature needs to be for the compound to melt or boil.
What indicates the presence of weak intermolecular forces in a liquid?
The characteristic that indicates the presence of weak intermolecular forces in a liquid is a low heat of vaporization. Another characteristic that indicates the presence of weak intermolecular forces in a liquid is a high vapor pressure.
Is the boiling point higher for compounds with a high viscosity?
Viscosity is the thickness of the compound. The thicker the compound the higher the intermolecular forces. The higher the intermolecular forces the higher the boiling point is.
What are physical properties of gasses?
Examples: low density, high compressibility, low viscosity, high diffusion, low intermolecular forces etc.
Do small molecules have high surface tension?
Generally larger molecules with stronger intermolecular forces have higher surface tension. This tendency can be seen if you look at the surface tensions of the alkanes. Water is a clear exeption to this pattern due to the very strong hydrogen bonds.
Do the molecules of alkanes have strong intermolecular forces and high melting points?
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.
What does a high melting point temperature indicate about a substance?
Strong Intermolecular Forces attract the molecules
What is a plausible reason for why a given liquid has a high viscosity?
Strong intermolecular bonds such as those caused by polarity or large string molecules that 'tangle' causing the viscous nature.
Are there strong forces of attractions between particles in a solid?
There are strong forces of attraction between particles in a solid.
How are the melting points of ionic compounds different from molecular compounds?
Very much higher.

Why gases show high compressibility?
The intermolecular forces in gases are very weak.
