# Which property of water best explains the high surface tension?

The high surface tension helps the paper clip – with much higher density – float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.

Click here to know more about it. Just so, which best explains the high surface tension of water?

its high density its ion-dipole interactions its adhesive interactions its hydrogen bonding interactions.

One may also ask, what are the 3 most important properties of water? The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen.

Also to know is, why does water have a high surface tension?

Water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds.

## What is the formula for surface tension?

The general formula for measuring surface tension is: gamma equals force divided by length. Gamma represents surface tension, F represents force, and d represents the length along which the force is felt. The units for surface tension are Newtons per meter (N/m) or dyne per centimeter (dyn/cm).

What factors affect surface tension?

There are three factors that affect surface tension.
• Temperature- the surface tension of a liquid decreases with increase in temperature.
• Soluble impurities – the presence of soluble impurities may increase or decrease the surface tension.
• Insoluble impurities- insoluble impurities decrease the surface tension.

### What is surface tension of liquid?

Surface Tension: “The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.” It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface.

### Does pH affect surface tension?

At pH < 0 the surface tension decreases signifi- cantly, indicating adsorption of HCl from strong acid solutions. At pH > 13 the surface tension increases, indicating a lower surface concentration of hydroxide ion than in the bulk solution.

### What are the application of surface tension?

Some notable applications of surface tension are: A needle placed on water can be made to float due to the surface tension of water. Warm water is used for washing purpose as heating increases the surface area and reduces surface tension. Mosquito eggs can float on water because of its surface tension.

### How do you measure the surface tension of water?

Place your penny on a flat, level surface where you can easily clean up a small amount of water, like on a kitchen counter. Hold the tip of the syringe over the center of the penny. Slowly press down on the plunger, allowing one drop of water at a time to fall onto the penny. Watch the penny very carefully.

### Why is water called the universal solvent?

And, water is called the “universal solvent” because it dissolves more substances than any other liquid. This is important to every living thing on earth. This allows the water molecule to become attracted to many other different types of molecules.

### What is mean by surface tension?

Medical Definition of surface tension

: the attractive force exerted upon the surface molecules of a liquid by the molecules beneath that tends to draw the surface molecules into the bulk of the liquid and makes the liquid assume the shape having the least surface area.

### What is the surface tension of water called?

The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. Equivalently, it can be stated as surface energy in ergs per square centimeter. Water at 20°C has a surface tension of 72.8 dynes/cm compared to 22.3 for ethyl alcohol and 465 for mercury.

### Why does surface tension occur in water?

The water molecules attract one another due to the water’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen cause water to “stick” together. This is why there is surface tension and takes a certain amount of energy to break these intermolecular bonds.

### What are 5 properties of water that are important to life?

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.

### Is water non polar?

Water (H2O) is polar because of the bent shape of the molecule. The reason the shape of the molecule isn’t linear and nonpolar (e.g., like CO2) is because of the difference in electronegativity between hydrogen and oxygen. The electronegativity value of hydrogen is 2.1, while the electronegativity of oxygen is 3.5.
