It is not possible to say why the density of a substance is proportional to mass or volume .

Generally speaking, the density of a substance is a definite quantity in a certain environment, and what can vary is the volume and mass of the substance. So although the formula is =m v, it is generally not said that density is proportional to mass and inversely proportional to volume, because this is easy to misunderstand, as if density can be changed at will. However, when comparing different substances, it can be said that the greater the mass of the same volume, the greater the density of the substance.

The density of matter is an intrinsic property of the object, and it cannot be proportionally equal by mass or volume, but it can only be said that the density of matter can be reflected by the volume corresponding to the mass. In other words, a substance can find a piece of such a substance and divide its mass by its volume to find the density of the substance. Be careful.

There are also things like resistance, capacitance, inductance, etc., which can not be discussed by your own thoughts.

The density of matter is a property of the substance itself and has nothing to do with external conditions, so it is wrong to say that the above statement is low. But we may calculate the density of an object from the mass of its volume.

Similarly, the resistance of the conductor is determined, independent of the applied voltage at the two ends of the conductor and the current passing through the conductor.

In physics, the mass of a substance per unit volume is called the density of that substance. Common unit: gram cm 3.

I don't know if you noticed, it's "mass per unit volume", so just saying "proportional to mass or volume" is incorrect.

Matter has nothing to do with mass or volume alone, it can only be said to be the ratio of mass to volume.

You are not correct to ask this question, the density of matter is a property of matter, independent of the volume of the object. The implicit condition of your question is that both objects are solid and composed of the same substance, and according to the definition of density, the density of the difference between the line of matter is equal to the ratio of the mass of the object to the volume of the object, and when the mass of Qingchong is constant, the larger the volume of the object, the smaller the density; Vice versa.

m=ρv,v=m/ρ

When v is the same, Li is wide, i.e. which or bright v=m1 1=m2 2

So when the volume is the same, their mass is proportional to the density of the dough.

Density is a kind of special foundation of matter, which is only related to the type and state of the branches and branches of the substance, and has nothing to do with the quality and volume of the object

So the answer is:

When the volume is constant, the density is directly proportional to the mass. This statement is false.

For the same substance, the density is a fixed value in a certain state, and it does not change with the change of mass or volume. When its mass (or volume) increases by several times, its volume (or mass) also increases by several times, and the ratio is constant. Therefore, it cannot be considered that the density of a substance is directly proportional to mass and inversely proportional to volume;

No, density is a property of an object, not arbitrarily changed, the definition of density is mass divided by volume, it cannot be said that density is proportional to mass.

Density is a property of matter that does not change with mass or volume.

But mass and volume are directly proportional.

Therefore, when the mass is constant, the density is not inversely proportional to the volume; When the volume is constant, the mass is not proportional to the density; When the density is constant, the mass and volume are directly proportional.

Wrong, because density is defined by the quotient of mass and volume, but not by volume. Definition and decision are two different concepts.

Density is a property of the substance itself, and it is fixed without changing the state of matter, temperature, etc.

No, because density is a property of matter, which is only related to the material, state, and temperature of the substance, and does not change with the change of mass or volume.

To be honest, this question is not easy to answer, but it can only be understood that the ineffable density mass volume is only a certain relationship in the calculation, you think, density is just a characteristic, for example, water, the density is 1000kg m. At a certain temperature and pressure, the density of one kilogram of water is like this, and the density of one gram of water is also like this, and the density will not change. The reason is that because the mass changes, the volume will change accordingly.

It would not be said that only one of the mass volumes is changed and the other is not changed.

So you understand that the density is constant at a certain temperature and pressure, and when the volume or mass changes, the corresponding mass or volume will also change accordingly, so the ratio will not change.

When doing the question, you have to insist that density is a property of the substance itself, and that those things like density that are proportional to mass and inversely proportional to volume are all wrong.

No matter how large or how large or how many objects of the same kind are, their density is the same. For example, the density of a palm-sized piece of iron is the same as that of a room, and it does not change depending on the volume.

m v is only related to the ratio of mass and volume.

To put it in layman's terms: no matter how heavy cotton is, it will float on the water, and no matter how small an iron ball is, it will sink to the bottom when it is put into the water.

The density of one gram of water is 1000kg m then 500g and 1000g ,...g Does water become denser?

Or 1000 kilograms per cubic meter, is it like this, is it related to volume and mass?

p=m v has its physical meaning, not a mathematical expression that says p is proportional to m or inversely proportional to v!

It's just that I'm afraid of a 0 0 situation.

The density of water is 1kg l

It's just that there is no water, the mass is 0, and the volume is 0

He also has a density of 1 kg l

Density is a property of matter, which is only related to the type and type of matter, and has nothing to do with the mass and volume of the object.

In physics, the mass of a certain substance per unit volume is called the density of this substance symbol A property of matter, it is only related to the type of substance, and has nothing to do with factors such as mass and volume.

To put it simply: the density of 1 L of liquid water is: 1 kg m, and the density of 2 L of liquid water is: 1 kg m. But the density of 1L of solid ice is m.

The answer to this question is simple.

Density really has nothing to do with its mass and volume.

But I think one of the more important lessons you should learn from this question is to figure out who determines who determines the physical quantities.

Is it the formula that determines the nature or the nature that determines the formula.

Otherwise, every time you encounter the same problem in the future, you have to ask it, wouldn't it be very troublesome, and you can write the formula here.

Density Quality

Volume, volume, mass, density.

Mass Density*

Volume however. The basic property of matter is density.

Because the quality can be increased or decreased.

The volume can be changed.

But density doesn't work (unless you're talking about average density in a macro sense).

Density is the property of a substance, not its volume or mass, but only the substance itself, such as iron or cotton.

The density has a basic formula for calculating the mass, that is, the density of the mass and the volume, the density of the same substance does not change, and the mass and volume are proportional to each other. Different substances, when the volume is the same, the mass and density are directly proportional.

There is a certain proportion relationship between volume, mass, and density, and there is no such thing as who decides who is determined by mu.

Yes, for a substance with a certain volume, the density can determine the mass, and the mass can also determine the density.

Density is an intrinsic property of an object, so it should be that the mass is proportional to the density, and the density determines the mass.

A kind of shed digging material with a certain volume", that is to say, the volume is fixed, the substance is also determined, the material is fixed, the density and the sum are also determined, and the quality is also determined.

It is only density that determines quality.
