* Volume measures the amount of space an object occupies. It's like the container size.
* Mass measures the amount of matter an object contains. It's like the weight of the contents.
Example:
Imagine a balloon filled with air and a brick of the same size. They have the same volume because they take up the same amount of space. However, the brick is much heavier because it contains much more matter.
Density plays a crucial role here:
* Density is the ratio of mass to volume. It tells us how tightly packed the matter is within an object.
* A denser object will have more mass in the same volume.
In summary:
* Same volume doesn't guarantee the same mass.
* Density determines the relationship between volume and mass.
