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.
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.
What does the oil do to the sea?
Oil spills in the sea can have detrimental effects on marine life and the environment. It can coat marine animals, making it difficult for them to move, breathe, and regulate their body temperature. Oil can also contaminate water, affecting the entire ecosystem and disrupting the food chain.
How do you find a surface tension by dripping silicone oil from a needle inside the water?
To find the surface tension of water using silicone oil, measure the diameter of the oil drop formed at the tip of the needle. Then, use this measurement and the height the drop falls before separating from the needle to calculate the surface tension by applying the Young-Laplace equation. The formula relates the surface tension to the radius of the drop and the difference in pressure across the drop interface.
In a 93 Olds Silhouette what would cause there to be oil in the water but no water in the oil?
Oil mixing with water in the cooling system of a vehicle can be caused by a leak in the head gasket. The head gasket may have failed, allowing oil from the engine to mix with the coolant. Water mixing with oil, on the other hand, is typically a sign of a failed head gasket or a cracked engine block.
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
How oil spills pollute the water?
Oil spills contaminate the sea and the fish die along with sea birds.
Can a water can be used for oil?
Yes, But unless it is cleaned very thoroughly it shouldn't be used for water again. Oil is very persistent and would contaminate the water.
Is used motor oil unsafe in soil?
Yes, it will eventually contaminate the water supply.
Can oil contaminate groundwater?
ground water is considered drinkable. Would you like to add some oil and drink it. Does that answer the question?
When walking on road in rainy season why so much petrol drop on road?
Oil floats on top of water.
How many drops of oil does it take to pollute a gallon of water?
A standard measure of oil pollution in water is 10 ppm (10 parts oil per 1,000,000 parts water). As a gallon of water weights 10 lbs (Imperial gal) or 8 lb (US) gal) the weight od a gallon is about 4.54 kg, or 4540 gm and there are usually thought to be 40 drops in a ml a drop of oil weighs about 0.02 gm.So 1 drop in gallon would be 0.02 gm in 4540 gm or 1 gm in 225000 gm (4 ppm). Indicating that 2.5 drops would pollute 1 gallon of water to the 10 ppm level
Is there such thing as a factory oil spill?
In a way. Oil storage tanks used by many industries can leak. This can contaminate ground water. I would refer to it as an industrial oil leakage rather than a factory oil spill.
Is oil toxic?
It depends on what kind of oil and how much oil you drink. If you drink just one drop of sunflower oil, then you will be okay, but if you drink a drop of gasoline, you would have a serious stomachache.
How much water polluted by one liter of oil?
One liter of oil can contaminate around one million liters of water. Oil pollution can have severe environmental impacts, affecting aquatic ecosystems and wildlife, as well as water quality for human use. Clean-up and remediation efforts are typically costly and time-consuming.
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.
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.
