When many water molecules form hydrogen bonds with other water molecules,
they form a lattice of water molecules
, which is strong and flexible. This creates a high surface tension. … As a result, this molecule at the surface tends to be pulled into the bulk of the liquid and thus minimizes the surface area of a liquid.
How is hydrogen bonding responsible for the high surface tension and low vapor pressure of water?
Water has high surface tension because of
extensive hydrogen bonding
. The vapor pressure of water is low due to hydrogen bonding. Vapor pressure increases as temperature increases.
Do hydrogen bonds cause water’s high surface tension?
Formed bonds are called hydrogen bonds which lead to
strong cohesive forces
between the water molecules and high surface tension of water.
How does the intermolecular forces of hydrogen bonding affect surface tension?
Stronger intermolecular forces will produce greater surface tension
. The intermolecular forces present in a sample of water are hydrogen bonds . … If the hydrogen bonds are removed or disrupted, the surface tension will decrease.
What intermolecular force is responsible for surface tension?
The cohesive forces between liquid molecules
are responsible for the phenomenon known as surface tension.
What liquid has the highest surface tension?
Besides mercury,
water
has the highest surface tension for all liquids, which is due to the hydrogen bonding in water molecules. The surface tension of water causes water molecules at the surface of the liquid (in contact with air) to hold closely together, forming an invisible film.
Which best explains the high surface tension of water?
The high surface tension of water is due to
the molecular interactions that are present between the molecules of water
. There are cohesive forces between the molecules in water. This high surface tension is also because of the polarity of the water molecule.
Which type of intermolecular attractive force is the strongest?
Explanation:
Ion-dipole forces
are the strongest of the intermolecular forces. Hydrogen bonding is a specific term for a particularly strong dipole-dipole interaction between a hydrogen atom and a very electronegative atom (oxygen, fluorine, or nitrogen).
Is high surface tension a strong intermolecular force?
Figure 11.4. 2: The Effects of the High Surface Tension of Liquid Water. … Note the correlation between the surface tension of a liquid and the strength of the intermolecular forces:
the stronger the intermolecular forces
, the higher the surface tension.
Is surface tension a strong intermolecular force?
Liquids that have strong intermolecular forces, like the hydrogen bonding in water, exhibit
the greatest surface tension
. Surface tension allows objects that are denser than water, such as the paper clip shown in B in the figure below, to nonetheless float on its surface.
What causes surface tension to break?
The stronger the bonds are between the molecules in water, the greater the surface tension. However, the surface tension of water can be broken by
adding certain substances such as detergents
. … Adding detergent to water weakens the bonds between the surface molecules, making them spread apart.
How do you determine the highest surface tension?
The greater the
intermolecular forces acting between liquid particles
, the greater the surface tension of the liquid. The attraction between particles in a pure liquid is known as cohesion, or as a cohesive force. Surface tension is dependent on temperature. Hot liquids have a lower surface tension than cold liquids.
How do you break the surface tension of water?
In order for water to flow more easily into these small spaces, you need to decrease its surface tension. You can do this by
adding soap
, which is a surfactant (a material that decreases the surface tension of a liquid).
What increases the surface tension of water?
The surface tension of water, for example, will increase
when highly soluble impurities are added to it
. When detergent is added to water, it decreases the surface tension of the water. Compounds that lower water’s surface tension are called surfactants, which work by separating the water molecules from one another.
Which has more surface tension water or oil?
Water has a high surface tension
(72 dynes/cm). … Oil differs from water in many respects, the most important of which is surface tension. Oil has a surface tension of 30–35 dynes/cm, meaning that oil-soluble fatty surfactants do not provide the desired surface tension reduction for oils.
Does throwing rocks break surface tension?
Nope
. The whole ‘breaking the surface tension’ is a myth. You would splat no matter how many bullets you had.
