Density is equivalent to the mass of a substance divided by the volume. If volume increases and mass stays the same, density will decrease. If mass increases and volume stays the same, density will increase.

∙ 12y agoYes you can change an object's density. You can melt a solid and turn it to a liquid, making the density decrease, because water is generally less dense than a solid, and the same can go for vaporizing water (water->gas). Changing the type of matter (solid, liquid, or gas) can result in density change, but keep in mind that some liquids can be considered denser than solids, example: corn syrup is denser than wood.
More generally, the density of many materials is temperature-dependent. The density of water at 20 degrees Celsius is not exactly the same as the density of water at 21 degrees Celsius.

∙ 12y agoNo it doesn't. The density of a material may vary by many things, most commonly pressure and temperature.
A ready example is the air. The air pressure varies constantly, in fact this is used in barometers which can be used to predict weather patterns, and so does the density of air.
Values found for the density of materials in books are usually valid only for 1 atmosphere of pressure and about 20 degrees Celsius.

∙ 13y agoDensity of objects does change:
density = mass/volume. If the volume of the object increases (thermal expansion for ex.) the density will decrease. The mass is what remains constant.

What is a density independent regulatory factor?
A density-independent regulatory factor is an environmental factor that influences population size or growth without being affected by the population density. These factors can include natural disasters like floods or droughts, temperature changes, or other abiotic factors. They have the same effect on population size regardless of the population's density.
Would the density of an ice cube have the same density as an iceberg the size of an entire school?
I would expect it to have more or less the same density, since it is made of the same material.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
Is the density of a kilogram of iron less than the density of 1 gram of iron?
No. That's the beauty of "density". It's a characteristic of the substance, and the size of the sample has no effect on it. As long as the sample is pure, a pinhead of it has the same density as a truckload of it.
Why is the density of a substance independent of sample size?
Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.
Will every object with the same dimensions have the same density?
No. Density is independent of size.
The density of a small piece of matter and a large piece of matter of the same matter are?
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.
Why is a golf ball heavier than a table tennis ball even though the balls are the same size?
Because its density.
Why a golf ball is heavier than a table tennis ball even though the balls are the same size?
Because its density.
Why a golf ball is heavier than a table-tennis ball even though the balls are the same size.?
Because its density.
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.
Will density always stay the same no matter what size the object is?
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
Does density change when the size of an object changes?
No. A drop of water and a tankerful of it have the same density. But these are two different masses of the same material. If you have, say a piece of metal and heat it up so that it expands, and there is still the same amount of substance, then the density decreases as the substance expands. Water expands as it freezes; that is why ice floats in water.
What is the difference between a box with high density and one with low density if they are the same size boxes?
If they're the same size, then the box with higher density has more mass, and consequently it weighs more when both are on the same planet.
What is a density independent regulatory factor?
A density-independent regulatory factor is an environmental factor that influences population size or growth without being affected by the population density. These factors can include natural disasters like floods or droughts, temperature changes, or other abiotic factors. They have the same effect on population size regardless of the population's density.
What effect does size have on the density of objects made of the same materials?
Well if they are made of the same materials then the density should be a constant or "the same."
