Short-Question

# How can an object have the same volume but different masses?

## How can an object have the same volume but different masses?

If the molecules are not closely packed together, the density of the substance will be less, meaning it contains less mass in a given volume ( cotton, air, etc.). This is the reason why different substances of same volume have different masses.

## What will happen if two objects have the same volume but one has a greater mass?

If the two objects have the same volume but different masses, the one with has a greater mass will have a higher density. For example each liter of gasoline and water don’t have the same masses.

Is it possible to have 2 different substances that have the same volume?

If two liquids have the same density, then any volume of the first substance will have the same density as any volume of the second substance. Changing the volume of a substance doesn’t change the density. As an example, mercury is a liquid metal whose density is 13.5 times that of water.

### Can the same liquid have two different masses?

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. The same amount of two different liquids you used in the container will have different densities because they have different masses.

### Will different substances with the same mass have the same density?

Density is a characteristic property of a substance. The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.

How can different sized objects have the same density?

Density is an intensive property. This means that regardless of the object’s shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density. It is because density in an intensive property of matter.

## Do objects have the same mass?

The object’s weight is less on Mars, where gravity is weaker, and more on Saturn, and very small in space when far from any significant source of gravity, but it always has the same mass. Objects on the surface of the Earth have weight, although sometimes the weight is difficult to measure.

## How can objects have the same volume but have different masses?

Density depends on mass and volume. Density = mass/volume. Things that have the exact same mass can have different densities if the volume associated with either are different. How is it possible for objects to have the same volume but different masses? Their masses are different. (Mass = density * volume)

How is density related to the volume of the object?

Density is defined as the mass per unit volume. This definition implies dividing the mass by the volume. When a number is divided by one you get the same number. If the divisor is replaced by 2, the quotient becomes smaller than one. Larger divisors produce smaller quotients. Since density is a quotient, it is greater when the volume is smaller.

### Can you make two objects have the same shape?

Nothing in the question says that the two objects are the same shape. Shape is far more important a variable. A 1g gold nugget will fall with negligible wind resistance. Take 2g of gold and pound it into gold leaf and it will flutter away on the wind.

### Can a balloon have the same volume as another balloon?

A given mass of air in a balloon would have the same volume as another unless one is heated or chilled. Or placed underwater. Heat expands the gases cold contracts them, and the pressure of the water would squeeze the air molecules closer together. Same with liquified air same mass much lesser volume.
