How can you modify a dense solid substance to make it float in a less dense fluidd?
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.
What else can I help you with?
How does an object's density determine whether the object will sink or float in water?
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
What is the analysis for can water float on water?
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.
If a mineral's specific gravity is less than 1 will it float?
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.
Can bar soap float?
No, a bar of soap is to heavy to float on anything.
What does the statement 'the buoyant force of a liquid does not depend on physical statebut on density' mean?
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.
How do you modify a solid to make it float in a less dense fluid?
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.
Will acid float on oil?
That depends what acid, and what oil, you are talking about. Basically the less dense substance will float on the denser substance.
The tendency of a less dense substance to float in a more dense liquid is called what?
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.
Why does one substance float over another?
A substance floats over another substance if it is less dense. Density is a measure of how much mass is in a given volume, so if one substance is less dense than another, it will float on top. This is due to the buoyant force exerted on the less dense substance by the denser substance.
How do you make a coin float?
make it less dense than the substance it is floating in.
What is the relationship between an objects density and the liquid density and the tendency of an object to float?
A less dense object or any other substance will float on a more dense liquid.
What is the relationship between object density the liquid density and the tendency of the object to float?
A less dense object or any other substance will float on a more dense liquid.
A substance floats or sinks in another because of its relative?
density. If the substance is less dense than the liquid it is placed in, it will float. If the substance is more dense than the liquid, it will sink.
Which property determines whether one substance will sink or float?
The density of the substance compared to the density of the fluid it is placed in determines whether it will sink or float. If the substance is denser than the fluid, it will sink. If the substance is less dense than the fluid, it will float.
How does a less dense substance move within a denser substances?
A less dense substance moves within a denser substance because of the difference in their densities, where the less dense substance will float or rise above the denser substance due to buoyancy. This movement is governed by Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object.
If substances of different densities were layered on top of each other the less dense will be on the top or bottom?
if they are all fluids than the less dense will be on the top and the most dense on the bottom but if there are solids than the solids will be in the order you put them in.
How does density effect substance ability to float or sink?
The density of a substance determines whether it will float or sink in another substance. If an object is less dense than the fluid it is placed in, it will float. If the object is more dense than the fluid, it will sink. This is because objects with a higher density displace less fluid and experience a greater buoyant force, causing them to sink.
