Does the same volume have the same mass?

Answer 1

Not necessarily. The mass depends on how close together the particles are. If the particles are further apart, the mass will not be as high as if the particles are closer together. So even if two objects take up the same amount of space, they may not weigh the same.

Answer 2

Not usually. 500 grams of styrofoam will take up much more space than 500 grams of iron. You must know the density of the substance to determine how much volume it will take up. Water has a density of 1g/cc, while Iron as I remember is about 13 g/cc.
therefore 1g of water would have a volume 13 times greater than 1 gran of iron.

Answer 3

Of course not. A quart jar full of air and a quart jar full of stones obviously

don't have the same mass. You can feel that by lifting one in each hand.

The weight you feel is directly related to the mass in each case.

Answer 4

(1) VOLUME

Objects with the same WEIGHT are not necessarily the same VOLUME.

[For example, a ton of lead and a ton of feathers both weigh the same, but their volumes would be completely different.]

(2) WEIGHT

Weight depends where you are: WEIGHT is affected by gravity but MASS is constant, so on the earth both the mass and weight of something are the same.

[For example, a man weighing 100 kg [14 Stone] on Earth, but if he went to the Moon he would only weigh one-sixth of that because the Moon's gravity is one-sixth that of Earth.]

(3) MASS

Mass is indestructible. No matter where you are in the universe your mass will never change

Mass can never be zero. Everything in the universe has mass. If it didn't it simply wouldn't exist

Mass is not related to gravity, centrifugal force, etc and these forces have no effect whatsoever on your mass

More gravity - the heavier the object. Less gravity - the lighter the object.

Unlike mass, weight can be zero.

[For example, an astronaut floating in space has no gravity acting on his body and, therefore, he has no weight]

Formula:

Weight (W) = Mass (M) multiplied by gravitational acceleration (g).

That is (W = mg)

This formula is Sometimes written as:

Force (F) = Mass (M) multiplied by acceleration (a).

That is (F = ma)

In summary:-

-The MASS and WEIGHT of the 2 objects would only be the same if they were both on earth.

[If not, use the formula to calculate the Weight]

Objects with the same WEIGHT are not necessarily the same VOLUME unless unless their density is the same. .

[on earth Volume is not affected by Density, but in space if gravitational attraction is less the Volume is greater. Just to make it complicated, then there's Inner Space.of Atoms.....! ]

Answer 5

No, the same volume does not necessarily have the same mass. The mass of an object is dependent on its density, which is the amount of mass per unit volume. Different substances can have different densities, so the same volume of different materials can have different masses.

Answer 6

If the objects have the same density, yes. If the object do not have the same density, then no.

Density = mass / volume.

Answer 7

Only if they have the same density. Aside from that, not. For example, 1 kilogram of water will have about 19.3 times the volume of the same mass of gold.
