Surface tension is proportional to cohesion: more cohesion equals more surface tension and less cohesion equals less surface tension. In other words, the more molecules want to stay next to each other, the less they want to spread out. This is usually a measure of intermolecular forces such as hydrogen bonding or London dispersion forces. These, in turn are a measure of the polarity of the intramolecular bonds. These, in turn are a measure of the difference in electronegativity of the component atoms of the molecule. Therefore, the greater the electronegativity difference, the more polar the bond, the greater the potential for intermolecular forces (given a non-linear molecule and non-tetrahedral molecule both of which shapes cancel out charge differences), the greater the cohesion, the greater the surface tension.

How do you measure surface tension and what methods are commonly used for this measurement?
Surface tension is measured by determining the force required to break the surface of a liquid. Common methods for measuring surface tension include the drop weight method, the capillary rise method, and the maximum bubble pressure method.
What are the factors affecting the surface tension?
The main factor is the strength of cohesion between molecules. For instance, water molecules have a slightly negative and a slightly positive end which makes them stick together like magnets. A molecule with more extreme positive and negative charges would have a stronger surface tension.
A measurement of how strongly particles attract one another at the surface of a liquid is?
A measurement of how strongly particles attract one another at the surface of a liquid is known as surface tension. Surface tension arises from the cohesive forces between liquid molecules, particularly at the interface with air or another medium. This phenomenon causes the surface to behave like a stretched elastic membrane, allowing small objects to float on the liquid's surface and affecting the shape of liquid droplets. Surface tension is typically measured in force per unit length, such as dynes per centimeter or newtons per meter.
Is Surface tension of water affected by potassium permanganate?
Potassium permanganate can potentially alter the surface tension of water, as it is a strong oxidizing agent. When added to water, it can break down organic compounds and reduce the surface tension. However, the effect may vary depending on the concentration of potassium permanganate and other factors.
How can one accurately measure surface energy and what methods are commonly used for this purpose?
Surface energy can be accurately measured using techniques such as contact angle measurement, surface tension measurement, and inverse gas chromatography. These methods help determine the interactions between a material's surface and other substances, providing valuable insights into its surface energy properties.
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
How do you break the surface tension?
Adding surfactants the surface tension decrease.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
Principle behind reading at the lower meniscus?
Reading at the lower meniscus means taking the measurement from the bottom of the curved surface of a liquid in a graduated cylinder or similar container. This is done to ensure an accurate measurement by avoiding the distortion caused by surface tension that can occur at the top of the meniscus.
What is surface tension coefficient?
Surface tension coefficient, also known as surface tension, is the force acting on the surface of a liquid that causes it to behave like a stretched elastic membrane. It is a measure of the strength of the attractive forces between molecules at the surface of a liquid. The higher the surface tension, the more difficult it is to break the surface of the liquid.
