If you had a scale, you could weigh the object to determine its mass. (Note that mass is not the same as weight, but the two are closely related insofar as we use weight to determine mass.) You could then carefully submerge it completely in water to determine how much water it displaced. That would tell you its volume. You would then divide the mass by the volume to get its density.
But what if you don't have a scale? Can you still determine its density? I think you can.
Place a known quantity of water in a graduated container. Carefully place the object in the container and note the change in the water level. Subtract the new water level form the old. That is the amount of water displaced by the object, which should be floating since it's less dense than the water. The weight of the water displaced by the object is equal to the buoyant force pushing up on the object.
What does this tell us? Well, since the object floats, we know that the buoyant force is equal (but opposite) to the weight of the object. In other words, if we know the magnitude of the buoyant force, we know the object's weight (and therefore its mass)! Now, you can divide its mass by its volume, which you determined earlier by fully submerging it.
Here's another wayDetermine how much water is displaced by the floating object. Then carefully fully submerge the object and record how much water is displaced. If you divide the first number by the second, you will know its relative density compared to the density of water!If the floating object displaces 100 ml of water and the fully submerged object displaces 150 ml, then the relative density is 100/150 = 0.667. Since the density of water is 1.00 g/cm3, that means the density of the object is 0.667 g/cm3.
You could float it in some other liquid other than water, such as salt water. Did you know that when you load a ship in fresh water the ship comes up some when it gets into the salt water of the ocean?
If it still does not float try floating it in Mercury.
You can increase the contact area between the object and the fluid by modifying the object by making it very flat or by attaching an object that has a much less density for example wings made of plastic on either side of the object like the wings of airplanes. the fast movement of the object over the surfice of the fluid can help.
2- Attaching air balloons to the object like flotation devises used in pool safety.
3- if possible you can increase the density of the fluid ,by for example by adding too much salt (with heating if possible) .
or
4- The volume of water displaced by the object must weight the same as the object, by modifying the shape of the object to make it like a bowl.
yes because liquid can be denser than say a beach ball that is why beach balls float in water.
attach helium or just air balloons to the substance because both air and helium are lighter than any other substance including oxygen
By putting it in something less dense then itself.
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
The ability for something to float on another substance is related to the density and since ice is LESS dense than water it would float on top of water, not water on top of ice.In other words, water is more dense than ice and thus no.
Yes. That's what specific gravity is all about - the comparison of the density of a material to that of an equal volume of water. If a material or substance has a specific gravity equal to that of water, its specific gravity (sometimes called "spee gee" by the chemists) is 1. If it is more dense, say twice as dense as water, its spee gee will be 2. If the spee gee of a substance, in this case a mineral, is less than 1, it is less dense than water and will float. There may be a few exceptions for porous materials, but this is the rule.
No, a bar of soap is to heavy to float on anything.
Floating, or buoyancy, depends on the density of the liquid and the density of the object. Water is a pretty dense liquid, and things float in it; they are buoyant. Oil or gasoline are less dense; things that float in water may not float in oil.
There is no known way to alter a object's density without chemically changing the substance. If you want it to float, remove enough of the substance so buoyant force could keep it afloat.
The tendency of a less dense substance to float in a more dense liquid is called buoyancy. Acids are substances that form hydronium ions when dissolved in water.
That depends what acid, and what oil, you are talking about. Basically the less dense substance will float on the denser substance.
Besides water, a substance in solid form is more dense. At the least dense substance floats, HN03 will not float in liquid HN03. ;)
make it less dense than the substance it is floating in.
A less dense object or any other substance will float on a more dense liquid.
A less dense object or any other substance will float on a more dense liquid.
If it can and in a gravity field, it will float to the top of the denser substance.
The density of the object goes through the less denser liquids until it gets to a liquid that is more dense than it. The first liquid that is denser than the object, the object will float on the liquid. My class did this in Science Class.
Type your answeIt is a dense substance, with a specific gravity between 5.6-6.0 r here...
An object will float when it has less density than the fluid or substance that it is placed in. The object floats upward due to buoyant forces. Similarly, objects will sink if they are dense than the fluid.
When two substances do not mix with each other, the less dense substance will float on the more dense substance. Vegetable oil floats on water. If the mystery substance with d = 0.95 g/mL does not mix with water, then it should float on top of water. If the mystery substance with d = 0.95 g/mL does not mix with vegetable oil, then it should sink in vegetable oil.
