Does soap affect the ability of the paperclip to float?
Yes, soap can affect the ability of the paperclip to float because soap lowers the surface tension of water. When the surface tension is reduced, the paperclip may no longer be able to stay afloat and could sink.
Is the process of adding dish soap to water in a sink a physical or chemical change?
The process of adding dish soap to water in a sink is a physical change.
Does dish soap sink or float on water?
Dish soap generally floats on water due to its lower density compared to water. This is because dish soap is less dense than water, causing it to float.
Why paper clips sink when added soap?
Soap reduces the surface tension of the water, making it easier for the water to overcome the buoyancy force of the paper clip, causing it to sink. This is because the soap molecules disrupt the cohesive forces between water molecules, allowing the water to spread out more easily and envelop the paper clip.
Is adding dish soap to water in a sink considered a chemical change?
No, adding dish soap to water in a sink is not considered a chemical change. It is a physical change because the substances involved do not undergo a chemical reaction to form new substances.
Does soap affect the ability of the paperclip to float?
Yes, soap can affect the ability of the paperclip to float because soap lowers the surface tension of water. When the surface tension is reduced, the paperclip may no longer be able to stay afloat and could sink.

The process of adding dish soap to water in a sink is a physical change.
Why can a carefully placed needle float on water even though it is more dense then the water?
Because of the surface tension: the attracting force between the water molecules, which effectively causes a "skin" on the top of the water. Drop a few drops of soap in the water and the needle will sink, because the soap weakens the bond between the water's molecules.
Does dish soap sink or float on water?
Dish soap generally floats on water due to its lower density compared to water. This is because dish soap is less dense than water, causing it to float.
Why does a penny sink faster in water than soap?
The density of a penny is higher.
How much water and soap is needed to remove a drop of oil from a aluminum surface?
you need 3 cups of water and about half a pound of soap to remove a drop of oil from an aluminum surface
Why paper clips sink when added soap?
Soap reduces the surface tension of the water, making it easier for the water to overcome the buoyancy force of the paper clip, causing it to sink. This is because the soap molecules disrupt the cohesive forces between water molecules, allowing the water to spread out more easily and envelop the paper clip.
Why does a blade sink on soapy water?
You can float a razor blade on water due to the 'Surface Tension' of the water. This is the tendancy of the water molecules to stay tightly together, which is why a water drop forms a 'hump' on a surface. Soap is a 'wetting agent', or surfactant. When you add soap to the liquid, the surface tension is drastically reduced, and the water molecules 'flow' around objects, like the razor blade. So, it sinks.
Is adding dish soap to water in a sink considered a chemical change?
No, adding dish soap to water in a sink is not considered a chemical change. It is a physical change because the substances involved do not undergo a chemical reaction to form new substances.
What will soap do to baby powder that is floating on water?
Soap will break down the surface tension of the water, causing the baby powder to clump together and sink to the bottom of the container.
Adding soap to water on wax paper?
Adding soap to water when it is on wax paper will cause it to separate. This will make it bubble up.
If you observe scum around the edge of the sink after using soap what might you infer was dissolved in the tap water?
The scum around the sink could be caused by hard water minerals like calcium and magnesium. When soap is used in hard water, it reacts with these minerals to form soap scum. Using a water softener or vinegar can help reduce the formation of scum.
