What can be assumed about the buoyant force on an object floating in water?
The buoyant force on a floating object is equal to the object's weight out of water.
What is the apparent weight for a body floating in water equal to?
if its floating, its zero : weight or force = upthrust from water note: upthrust from water = weight of water displaced
How can you compare the density of oil and water?
Take 2 containers Fill 1up with water About 3/4 full. Take the other container and fill it with the exact same amount of oil. Take a rectangular floatable object. Weigh it, then put it in the water. mark the water line. Dry the rectangular floatable object so that it is completely dry. Now put it in the tub of oil. mark the oil line. Since oil is lighter than water, it should float higher in the oil. Ie: floating box is 6'' high. In the oil your mark is @ 3 inches from bottom. In the water it is 4 inches from the bottom. the weight of your box is 10 Gram's, oil is 2/3 the density of the water. It is called displacement. Hope this helps you.
How do you remove oil from water?
Oil and water are often separated by density--the oil floats to the top and the water is drained from the bottom. Oil and water can be separated by temperature--Oil usually boils at a higher temperature. Also oil and water freeze at different temperatures. Oil might solidify and is easy to remove in clumps. Oil can be separated from a surface by skimming. A rotating disk lifts up the oil and a blade skims it off the disk. There are filters that pass only water, not oil, and others that work in the reverse. A wick floating on the surface oil will burn off the oil. Lots more ways.
Why does a ship floating on water move?
because the water carries the ship along with its current
Physical changes of oil and water?
is water and oil a physical change or chemical change.
Why does water weigh more than cooking oil?
It dosent, waters density is lower then cooking oil, resulting in cooking oil floating on water
Which has the lowest density between cooking oil and water?
The oil is floating on water, so it density is lower than that of water.
Why does oil in a bowl of water get repelled when washing liquid is dropped on it?
The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.
How the nonpolar character of oil molecules helps when removing oil from water?
Oil molecules are nonpolar, so they will not mix with polar water molecules. This characteristic helps when removing oil from water using nets and floating barriers is that oil molecules won't mix with water molecules and the oil molecules float. Because oil floats on water, the oil can be skimmed off the top of the water.
What happens when lightning hits oil?
As in oil floating in a body of water such as, say...the Gulf of Mexico, the lighting discharge would ignite the oil on the surface, and it would burn.
How do you know if ahead gasket is going out for a jaguar xtype?
rough running, water or emulsion in oil, oil or emulsion in water (floating on water in top of radiator), steam from exhaust, compression test to check.
Does motor oil sink or rise in water?
It rises in water Source(s) - i did that for my science project in 5th grade ADDED: It does indeed, ending up floating on the water's surface because oil is less dense than water.
What is a oil sick?
Oil of the Sick is an olive oil blessed by bishop just before Easter, that is used to anoint those who are seriously ill in the sacrament of Anointing of the Sick.DO YOU MEAN AN OIL SLICK??This refers to oil floating on water. Oil from an oil spill or similar.
A thin layer of oil with index of refraction 1.28 is floating on water what is the minimum thickness of the oil in the region that reflects green light of wavelength 536 nm?
.05 mm
Icebergs ?
A lage chunk of ice floating in the water, most of it is in the water.
Why is water alone not able to wash the oil from sea birds?
Crude oil, like any other oil does not dissolve in water. So soap is needed as a releasing agent to make it come off the animal. The oil makes the animals fur or feathers useless for repelling water for floating and the oil poisons the animal when they consume it while cleaning it off themselves.
