Why is it that an half of an object is denser than the whole object?
That's not true at all. The whole idea of density is that it doesn't depend on the size of the sample; big samples and small samples of the same substance have the same density. If the whole object and a piece of it have different densities, then you can bet the composition of the piece is different from the composition of the whole thing. Example: The whole object ... a rock glued to a surfboard ... has low density and floats. One piece of it ... the rock ... has high density and sinks. (Another piece ... the surfboard ... is even less dense than the complete object, and floats even better.)
Do snakes shed peice by peice?
They actually shed they're skin as a whole
What influences whether or not an object will float the most?
The relationship between the object's volume and its weight, commonly combined in a single number called the object's 'density'. That's the whole story right there, in a nutshell, and it doesn't even have anything to do with the object's size. If the object's density is less than the density of the substance you drop it into, it floats. If greater, it sinks. You can't get any more direct than that.
Does the size of an object change an object's density and why?
No. To calculate density you divide mass by volume (d = m/V) If you double the size of something (volume), then you are doubling the amount of it (mass). The whole reason for using density to compare things is because it is a property of the substance that does not change, regardless of quantity.
If 90 percent of an object is floating below water what is its density?
Let's say the object has mass M and volume V. An object floats by displacing an amount of water equal to the object's mass. So water equal to 90% of the volume of the object has mass equal to the whole object, or M = 0.9V * 1g/ml or M = 0.9V Since density is mass divided by volume, or d = M/V, density of object = M/V = 0.9 g/ml.
Why did different size of blocks of wood have the same density?
Density isn't determined by the size of the specimen but by its mass per unit of volume. An oak branch has the same density as the whole tree it came from--the weights are vastly different, but density is the same.
Does density vary with the of volume of a body?
The density of an object is its mass divided by its volume.The density of an object varies inversely with its volume.Thus, if you can compress and object, like a sponge, you can increase its density.Normally, we say the density of a type of material is an intrinsic property, i.e. if you have a big piece of it or a small piece of it, they both have the same density because the large piece has a proportionately larger volume than the small piece.So, a gallon of water has the same density as a milliliter of water.Note the distinctions here.1. An object, like a car, can be made of many different materials and the object, as a whole, has some density which is the mass of the car divided by the volume of the car. If you crush the car, you increase its density.2. Each type of material also has a density. The glass in the window of the car has its own density, a property inherent in that type of glass. The steel in the car has the density of steel, a property inherent in that type of steel.If you have a type of material and you compress it, you increase its density.If you don't compress it, then two different pieces of the same uniform material, large or small, will have the same density under the same conditions of pressure and temperature. That is what we mean by density is an intrinsic property of a material.
Can you use mass and volume to predict whether the object will sink or float in water explain?
No. Density is mass per unit volume, but density of an object compared to density of water isn't the whole story. A boat may be very massive, and have a lot of volume, such that it is denser than water taken as a whole. But it still floats. A rock, on the other hand, is also denser than water, but it sinks.
Does cutting an object in half change the density?
The density of something is the mass divided by the volume, so if you cut the item in half, it will not change the density at all. Instead, the two halves of the item will have the same density.
Density of an object?
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
Is this right- changing the shape of an object has no effect on the density because it has the same amount of particles and the same amount of shape?
Yes, that's correct. And even if you glue or weld ten of the same object together into one big blob, the whole blob still has the same density as one of the little pieces has.
What is density Give density of water?
Density=mass/volume density of water in the whole earth is 1
