From wikipedia:
"The cohesive forces among liquid molecules are responsible for the phenomenon of surface tension. In the bulk of the liquid, each molecule is pulled equally in every direction by neighboring liquid molecules, resulting in a net force of zero. The molecules at the surface do not have other molecules on all sides of them and therefore are pulled inwards. This creates some internal pressure and forces liquid surfaces to contract to the minimal area."

Does ethylene glycol molecules have a greater attraction for cyclopentane than for each other?
False
Why do some liquids have greater viscosity than others?
Viscosity is determined by the internal friction between the molecules of a liquid. Factors such as molecular size and shape, intermolecular forces, and temperature influence viscosity. Liquids with larger and more complex molecules, stronger intermolecular forces, and lower temperatures tend to have greater viscosity because the molecules have a harder time sliding past one another.
Is Sucrose soluble in water because the attractive forces between the solute particles are greater than the attractive forces between the solute and the solvent particles?
You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

Which has a greater attraction for electrons Fluorine or Oxygen?
when compared to oxygen, fluorine has greater electronegativity (greater attraction for shared pair of electrons).

False
What makes one solid more dense than another?
Force of attraction make a solid denser. Solids have great force of attraction between their molecules that's why they are denser. Greater would be the force of attraction greater would be the density.....

when compared to oxygen, fluorine has greater electronegativity (greater attraction for shared pair of electrons).
Which has a greater attraction for electrons Ca or O?
Oxygen has a much greater attraction for electrons than calcium does.
Do ethlyene molecules have a greater attraction for each other?
Yes, ethylene molecules have a greater attraction for each other due to the presence of a double bond between the carbon atoms. This double bond creates a stronger intermolecular force called a pi bond. This results in a higher boiling point and stronger molecular interactions compared to other hydrocarbons with only single bonds.
Why does me and my friend near each other doesn't feel force of attraction?
because for attraction mass of one object should be greater than other
The speed of sound is greater through a solid than through a gas because the molecules in a solid are?
The speed of sound is greater in solids. This is because the molecules in solids are closely packed. This allows sound to move faster.
Why are you NOT weightless on the moon?
Because the Moon has mass, a LOT of mass. If something has mass, it will have gravitational attraction. The more mass, the greater the attraction. The moon has ~1/6th the gravity as the Earth.
Why alcohol exist in a liquid state while smaller hydrocarbon tend to be gases?
Precisely because of the size of the molecules. Larger molecules have a greater tendency to stick together, because there are more places where they can interact, and thus, a greater total force.
