Why does density always stay the same regardless of the mass?
Density is defined as mass divided by volume. If you take two samples of the same material, and one of the two has twice the volume, then it will also have twice the mass - since it is characteristic for a certain material to have a certain amount of mass per volume (i.e., a certain density). Thus, if you take a liter of water, you'll have a mass of one kilogram; two liters of water will have a mass of two kilograms. Divide twice the mass by twice the volume, and you still get the same result.
Why can two objects with the same mass have different densities?
Volume. 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 does decreasing the mass change the object's density?
Density is mass divided by volume. If the volume remains the same, decreasing the mass decreases the volume.
How to convert density to mass?
density is mass/volume so if you multiply the volume you want to convert you get mass but you have to make sure that the volume units are the same
If you cut a cube in half will the combined volume of the 2 halves be more less or the same?
The volume will stay the same, because you are not taking any volume away, nor adding any. Therefore the volume will stay the same.
When you heat a cool substance does the mass or volume change?
No, the mass and volume stay the same but the shape changes. Changes in state never change it's mass but if it changes to gas, the volume is unmeasurable.
What is the same with mass and volume?
Any volume of non-vacuum anything has mass. Any mass has volume. Both mass and volume have an 'm' in the word. Other than that, they are not at all the same thing.

Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume

Volume. 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.
If A sponge and a brick that are the same size they have the same what?
no; they have the same volume but their mass is quite different; density is mass/volume and the sponge has much lower density
How do you calculate the density of a substance?
Density is the mass of a substance divided by the volume of that same mass of substance.
What will happen to the mass volume and density if you chop the wooden block in half?
The volume will be reduced to a half of its original value. If the mass is (approximately) evenly distributed throughout the wooden block then the mass will also reduce to a half of its original value and the density will not change.
Can objects with the same mass have the same volume?
no
Does your mass increase decrease or stay the same if you so to Saturn?
Your mass will stay the same no matter where you go.
How does decreasing the mass change the object's density?
Density is mass divided by volume. If the volume remains the same, decreasing the mass decreases the volume.
Why does mass and volume affect density?
The density of a substance is its mass divided by its volume. So for the same volume the higher the mass, the higher the density.
