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 the tightness across the surface of water is called?
Surface tension is the tightness across the surface of water caused by the attraction between water molecules.
Why does water bead up on a smooth surface?
Water beads up on a smooth surface due to surface tension, which is caused by the cohesive forces between water molecules. This surface tension minimizes the contact area between water and the surface, causing the water to form beads to reduce the energy required to maintain the surface tension.
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.
Why would a needle flaot on the water?
A needle can float on water due to surface tension. The surface tension of water is strong enough to support the needle and prevent it from sinking, as long as the needle is carefully placed on the water and doesn't break the surface tension.
A consequence of the surface tension of water is what?
capillary action is a common consequence of surface tension.
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.
Which of the following is not a consequence of force A Weight B Surface tension C Gravitational pull D Magnetic force E Electrical force?
Surface tension is not a consequence of force. Surface tension is a property of liquids that arises due to intermolecular forces acting at the surface of the liquid. It is not a force acting on an object.
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 property of water let's bugs walk on water?
surface tension
How does surface tension of water compare with the surface tension of most other liquid?
The surface tension of water is higher than that of most other liquids. Water has a surface tension of 7.29 * 10-2 J/m2 at 20oC.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
What is the tightness across the surface of water is called?
Surface tension is the tightness across the surface of water caused by the attraction between water molecules.
How do the word use surface tension?
A water skipper is able to walk on water based on surface tension.
Does density of water increase or decrease the surface tension of water?
The surface tension of water is due to cohesive forces between water molecules. Density does not directly affect surface tension, but impurities or additives can alter it. Essentially, the surface tension of water remains constant regardless of its density.
What property of the structure of water allows water spiders to walk across the surface of a pond?
it is when water molecules in the water form a 'wall'.Pond skaters have legs that spread out away from their bodies, lowering the pressure exerted by their weight and not breaking the surface tension of the water
Is surface tension and water tension the same?
yes
