You have two choices:
-- Somehow increase or decrease its mass without changing its volume.
This is quite difficult.
-- Somehow either expand it into a greater volume or squeeze it into a
smaller one, without changing its mass in either case. This is easy to do
if the object happens to be a sample of a gas.
To change an object's density, you can change either its mass or volume. Increasing the mass or decreasing the volume will increase the density, while decreasing the mass or increasing the volume will decrease the density.

How does the density of an object effect its gravitational pull on other objects example when a star's density increases its gravitational pull increases on other objects?
Mass, not density, and the closeness of objects, affects an object's gravitational pull. Density is not dependent on an object's size, but mass is. The more massive an object, and/or the closer an object is to another, the greater its gravitational pull.
Does the density of water change as a function of dissolved salt?
Yes, the density of water increases as salt is dissolved in it. This is because the salt adds mass to the water without significantly changing its volume. The increase in density allows objects to float more easily in saltwater compared to freshwater.
What happens to the density of nearly all objects as they cool down?
As objects cool down, their density typically increases. This is because the particles in the object lose kinetic energy and move closer together, causing the object to become more compact and denser.
What term describes the comparison of an objects mass to its volume?
density
What does density refer to?
Density refers to how much mass an object has in a given volume. It is a measure of how tightly packed the particles in a substance are. Objects with high density have more mass in a given volume compared to objects with lower density.
If an objects volume is unchanged then how will its density change?
It won't change. Density is volume divided by mass, so if volume doesn't change, density doesn't change unless you change the mass of the object.
How does density change with different objects?
The density changes with different objects as all have different mass and volume(the space an object occupies) and the more compressed(Compact) the object is the more density it has.
Can objects change their density?
Yes! I'm glad you asked! An object can vary with density, but only so. Example: If an objects density is, say, 6.7, it would NOT be able to increase to 9.8. Say you have a gummy bear, and it's density is 1.5. It may very well change to 1.8, or 2.0. But not to 3.0.
How does a change volume affect an objects density when mass stays the same?
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
Hoe does an objects density determine whether the object will sink?
If an objects density is less than the density of what it is put in it will float. If the objects density is greater it will sink.
What determines objects density?
An objects density is determined by its' weight and volume.
What determines an objects density?
An objects density is determined by its' weight and volume.
Why is volume extensive?
Volume is extensive because it depends on the amount there is unlike an intensive property such as density because and objects density will never change no matter how much there is of it.
How can an objects density change?
An object's density can change by altering its volume or mass. Increasing mass while keeping volume constant will increase density, and vice versa. Similarly, decreasing volume while keeping mass constant will increase density, and vice versa.
Do heavier objects have a higher density than lighter objects?
Not necessarily. Density is determined by the mass of an object compared to its volume. Heavier objects may have a higher density if they are more compacted, but lighter objects can also have a high density if they are very compacted or have a smaller volume.
What effect does size have on the density of objects made of the same material?
Well if they are made of the same materials then the density should be a constant or "the same."
What objects gives buoyancy?
Buoyancy is linked to density, density being how much material is packed into an object of a certain size. Objects with less density will generally be buoyant in more dense objects.
