What is the shape of a drop of oil placed in the surface of water?
A drop of oil placed on the surface of water will typically form a near-perfect circle due to surface tension forces that minimize the surface area of the liquid.
Why does a drop of water placed on the surface of oil contracts to form a spherical shape?
The surface tension of the water and the fact that oil and water cannot wet each other.
Does the amount of iron filings in water effect waves when a magnet passes over?
No, the amount of iron filings in water does not affect waves when a magnet passes over. The iron filings would be attracted to the magnet, creating a visual effect, but they do not disrupt the propagation of waves in the water.
What forms when water slowly bubbles underground?
When water slowly bubbles underground, it can form geysers or hot springs. Geysers erupt intermittently, releasing steam and water into the air, while hot springs have a constant flow of warm water to the surface. Both are caused by underground volcanic activity or geothermal heating.
Does a paperclip float in water?
Yes a paper clip is able to float in water. Take a bowl, fill it up to the top with water, take a paper towel and put it into the bowl, let it sit there for 3 seconds...then put the paper clip on it, and slowly remove the towel. This is able to work by Surface tension.Depending on the size, some paperclips can due to the high surface tension of water.
What will happen to a needle place in 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.
What is the shape of a drop of oil placed in the surface of water?
A drop of oil placed on the surface of water will typically form a near-perfect circle due to surface tension forces that minimize the surface area of the liquid.
How do you separate table salt aluminum filings iron filing?
Use a magnet to remove the iron filings. The add water to dissolve the salt, and the aluminum filings will settle to the bottom of the container. Pour that salt water into a pan, heat it and evaporate the water, leaving the salt in the pan.
What technique will use to separate ashes and iron filings with water?
separate iron filings AND ash from water by filtration or evaporation then, if required, separate iron filings from ash by using a magnetic field,
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.
Why does a coin placed in a basin filled with water appear to be nearer the surface of the water?
because it is refracted.
Why does a drop of oil placed on the surface of water spread over the entire surface?
Oil is less dense than water and has a lower surface tension. When a drop of oil is placed on water, it spreads out to increase its surface area and minimize contact with water molecules. This process is driven by the intermolecular forces between the oil and water molecules.
What happens to a solid object when density that is less than water when it is placed in water?
it floats.They float at water surface.
What happens to a solid object with density that is less than water when it is placed in water?
it floats.They float at water surface.
Why does a drop of water placed on the surface of oil contracts to form a spherical shape?
The surface tension of the water and the fact that oil and water cannot wet each other.
How do you separate mixture of iron filings water and clay?
evaporate the watercrush the clay-iron mixture to powderuse a magnet to remove the iron from the clay
What would happen to a fresh water cell if placed into salt-water?
die..and its body will float on the surface
