Yes it is not possible. Because as soap is added then surface tension would get reduced and so possibility of float becomes less. When we carefully place the same needle on ordinary water floating is quite possible as water has more surface tension
Yes if the surface tension of the water is not broken. If you are careful you can place a needle on the surface of the water in a glass. Also if you reduce the surface tension with detergent (just a very little is enough) the needle will sink because it's density is greater than that of the water. NO (if the surface tension of the water is broken, a needle cannot float on the surface of water. This is because the needle has higher density than water (density is mass divided by volume).
Because needles density is higher than water
Soapy water will hold more on a penny compared to pure water. This is because the surface tension of soapy water is lower than that of pure water, allowing it to spread out more and cover the penny's surface.
Rubber ducks float in the bathtub because they displace water and are less dense than the water around them. This buoyancy allows them to stay on the surface of the water rather than sinking.
Octane is less dense than water, so it will float on the surface of water.
A needle can be made to float on very still 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.
Yes, a needle can float on water if it is carefully placed on the surface due to surface tension. However, if the needle is pushed down into the water, it will sink due to its density being greater than that of water.
A needle placed in water will float due to surface tension. The surface tension of water allows the needle to be supported on the surface rather than sink.
A needle can float on water due to surface tension. The water molecules at the surface stick together, creating a "film" strong enough to support the needle's weight without it sinking. This phenomenon is also why some small insects like water striders can walk on water.
Fleas jump into soapy water because the soap reduces the surface tension of the water, making it difficult for them to float and escape. This causes them to sink and drown.
A needle will sink in water because it is denser than water. The buoyancy force acting on the needle is not enough to counteract its weight, causing it to sink.
Surface tension of water is the property that allows a needle to float on water. This is due to the cohesive forces between water molecules at the surface, creating an invisible film strong enough to support the needle's weight without breaking.
Due to surface tension, the upper surface of water acts like a stretched membrane which enables it to float a swing needle.
Surface tension
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.
