What is the difference between surface tension and surface free energy?

The main difference between surface tension and surface energy is that surface tension measures the force per unit length of the surface while surface energy measures the amount of work that needs to be done per unit area in order to stretch it. …

What is the relationship between surface free energy and surface tension?

Hence, surface tension = surface energy per unit area. Thus, surface tension is equal to the mechanical work done per unit surface area of the liquid, which is also called surface energy.

What are 3 surface tension examples?

Examples of Surface Tension

• A Drop of Liquid.
• Soaps and Detergents.
• Washing with Hot Water.
• Clinical Test for Jaundice.
• Water Striders.
• Capillary Action.
• Formation of a Meniscus.
• Bubbles.

What is the difference between surface tension and viscosity?

Surface tension can be considered as an incident that occurs in liquids due to the unbalanced intermolecular forces, whereas viscosity occurs due to forces on moving molecules. Surface tension is present in both moving and nonmoving fluids, but viscosity only appears in moving fluids.

What type of energy is surface energy?

Surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created. It is also called as surface free energy or interfacial free energy. In simple language, surface energy can be defined as the work per unit area done by the force that creates the new surface.

What is surface tension explain?

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 cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.

What is surface tension and example?

surface tension, property of a liquid surface displayed by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles. The razor blade is not floating: if pushed through the surface, it sinks through the water.

What is the difference between surface tension and cohesion?

The key difference between cohesion and surface tension is that cohesion describes the intermolecular forces occur between identical molecules, whereas surface tension describes the property of elasticity of the surface of a liquid.
