Density of the substance will always stay the same. Density of the object will also stay the same if solid, no matter the size, but not if it is carved out. That is why a steel boat can float
The same as when it is in air, unless the object interacts with either water or air, or both (in different ways). Density is dependant on the object's mass and volume and has nothing to do with the medium in which it is sitting, unless that medium interacts with it in some way.
Yes, the density of an object has no relation the number of pieces that the object is divided into, nor to the size of the obect. For example: The density of 1 pound of steel is exactly the same as the density of 1 ton of identical steel, and the density of 1 mL of water is exactly the same as the density of one Liter of water. That is the textbook answer, in real life most cutting techniques disturb the boundary of the cut line. So if you want a real to life answer then the density is only changed at the cut line where temperature and pressure will effect the structure of the metal being cut. Textbook answer is density remains unchanged throughout the whole of the material no matter how many times you cut it. think of density as "how hard something is packed together at the molecular level". This is a ok way to look at density. Cheers!
Mass and densityDensity is defined as mass per unit volume. For example, the kilogram is the fundamental SI unit of mass. The kilogram per cubic meter and the gram per milliliter are examples of units of density. The concept of density's relationship with weight maybe that when considering two objects with same mass (i.e same quantity of matter contained) and same volume(i.e same space occupied);the one with the greater density(more denser) will be more heavier than the less denser object .This depends upon the different materials they are made up of.the denser object is more in weight probably (that is what i conclude) due to the absence of any other medium molecules in between the molecules of the material (in the molecular space)that constitutes the object unlike the less denser object which may have other surrounding medium's molecules in the intramolecular space......because practically there no vaccum in the intramolecular space of a particular gas but there are molecules of air between them
You cant, the mass will always be the same, NO matter what.
false
No. Density is a characteristic property, so there it is always the same no matter how much of the substance is present.
Will always float with the top surface level with the water
Yes all aluminum blocks have the density of 2.7g/cm3, this is because the density always reamains the same... mass will be used when you have to find the quantity of matter inside an object... and weight is the pull of gravity on that object. So if you do the formula- density =mass all over volume it will give you the correct density.
no. the density of an object is alone no matter how much you have it is still the same if i have a glass of water its density is 1 if i have an ocean of water its density is 1
yes, very often its one of the best things to messure things with. Didn't you pay attention in 6th grade scinence?
Since Density=Volume/Mass, and the mass increases as the volume increases they will always have the same density no matter how big it is.
1g/mL Density is an intensive property so no matter the amount of water, its density is always the same.
The answer to that question is: No. The density of an object only depends on the substance its made of. If two samples are made of the same substance, then it doesn't matter if one is the size of a grain of sand and the other is the size of a battleship ... they have the same density.
No. There will always be more density (however small) when you increase the size or amount of something
That it will always fall at the same rate no matter how hight you are
It is useful because no matter how much you have of the same substance, it will always have the same density. The mathematical equation to find the density of matter is to divide the mass by the volume. So you get an average, the density. Water has a density of 1. However, oil has a density of something like .9, so it floats on water. That way, by just looking at the numbers, you can tell what is what.
If the material is pure and homogeneous, i.e. "the same throughout", then the density is independent of the size of the sample. A chip the size of a pinhead and a chunk the size of a truck have the same density.
