What causes the surface tension and high boiling point in water?

What causes the surface tension and high boiling point in water?

Correct answer: Cohesion and hydrogen bonding are the cause for water’s low vapor pressure, high boiling point, and high heat capacity. Adhesion is water’s property to adhere to a surface, and is the cause of capillary action.

What factors affect the surface tension of water?

Surface tension is caused by the effects of intermolecular forces at the interface. Surface tension depends on the nature of the liquid, the surrounding environment and temperature. Liquids were molecules have large attractive intermolecular forces will have a large surface tension.

What explains high surface tension?

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.” The high surface tension helps the paper clip – with much higher density – float on the water.

Why does water have an increased surface tension compared to most other liquids?

Besides mercury, water has the highest surface tension for all liquids. Water’s high surface tension is due to the hydrogen bonding in water molecules. Water has very strong intermolecular forces, hence the low vapor pressure, but it’s even lower compared to larger molecules with low vapor pressures.

What causes 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.

What causes the high surface tension low vapor pressure and high boiling point of water?

Many unique and important properties of water—including its high surface tension, low vapor pressure, and high boiling point—result from hydrogen bonding. The structure of ice is a regular open framework of water molecules in a hexagonal arrangement. Water molecules are held together through hydrogen bonds.

How can you reduce the surface tension of water?

Some liquids such as oil and kerosene can destroy surface tension in water. Adding soap or detergent reduces surface tension in water. Increasing the temperature of the liquid reduces surface tension.

Why does salt water have a higher surface tension than water?

Complete answer: The surface tension of water is increased when salt is added to it. This means that molecules near the surface have more energy, which manifests as an effective force that ‘pulls’ water molecules inwards and reduces the surface area.
