Here's why:
* Density: Density is a measure of how much mass is packed into a given volume. Changing either the mass or the volume will directly affect the density.
* More mass, same volume: Increased density
* Less mass, same volume: Decreased density
* Same mass, more volume: Decreased density
* Same mass, less volume: Increased density
* Weight: Weight is the force of gravity acting on an object's mass. Since changing the mass directly affects the force of gravity, the weight will also change.
* More mass: Increased weight
* Less mass: Decreased weight
Important Note: While weight is directly related to mass, it is influenced by gravity. So, if you were to change the location of the object (like moving it to the moon where gravity is weaker), its weight would change even if its mass remained the same.
