What is the difference between shear stress and normal stress?
Shear stress is the force applied parallel to a surface, causing it to slide or deform. Normal stress is the force applied perpendicular to a surface, causing compression or tension.
What is the difference between tension and pressure in physics?
In physics, tension refers to the pulling force applied to an object, often through a rope or cable. Pressure, on the other hand, is the force applied perpendicular to the surface of an object, typically measured as force per unit area. In summary, tension acts along the length of an object, while pressure acts perpendicular to the surface of an object.
Effect of impurities on surface tension of liqiud?
yes The presence of impurities either on the surface or dissolved in it, affect surface tension of the liquid. Highly soluble substances increase the surface tension of water, whereas sparingly soluble substances reduce the surface tension of water. The surface tension of a liquid decreases with increase in temperature. The surface tension of a liquid becomes zero at its boiling point and vanishes at critical temperature.
What does surface tension have to do wih floating?
Surface tension is the property of a liquid that allows it to resist external forces. When surface tension is strong enough, it can support the weight of certain objects on its surface, causing them to float. This is because the surface tension creates a "skin" on the surface of the water that can support the object's weight without sinking.
What makes a needle to float in water?
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
What is a force applied to a confined fluid?
Surface Tension happens

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.
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.
What is a force that acts on particles at a liquids surface?
Surface tension is the force that acts on particles at a liquid's surface. It is caused by the cohesive forces between the liquid molecules, which creates a barrier that resists the penetration of external objects or forces. This force is responsible for phenomena such as capillary action and the formation of droplets.
Effect of Temperature on Surface Tension?
surface tension decreases with the increase of temperature
How does temperature affect surface tension?
As the temperature rises, surface tension decreases.
Is surface tension a solid liquid or gas?
Surface tension is a characteristic of liquids.
What is surface tension in hydrocarbons?
Each liquid hydrocarbon has a different surface tension.
