|
|
|
amount of matter per unit of volume( brick is more dense than foam)
|
|
|
amount of energy per unit of density( brick is more dense than foam)
|
|
|
Either A or B
|
|
|
None of the above
|
Detailed explanation-1: -The brick is denser than the sponge because it contains more mass per unit of volume than the sponge does. Different types of matter have different densities. So, density can be used to identify a substance.
Detailed explanation-2: -Density = Mass/Volume also means that the larger the volume of an object compared to its mass, the less dense it is. For example, if a marble weighs the same as a much larger foam ball, the marble has a higher density than the foam ball, despite its smaller size.
Detailed explanation-3: -Density – How much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). The amount of mass per unit of volume. lot of space, it has low density. Measured in gm/L or mg/mL.
Detailed explanation-4: -When volume increases, density decreases.
