Because every material has its own density. Examples:Solid - water - noble gas

Copper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.

Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.

Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =

0.0001785 g/cm3 = 0.0001785 g/mL.

Can you use density of an object to predict whether it will float or sink in water?

Yes, you can use density to predict whether an object will float or sink in water. If the density of an object is less than the density of water (1 g/cm³), it will float. If the density of an object is greater than the density of water, it will sink.


How can you use math to predict if an object will float or sink?

If the object's density is greater than the density of the liquid in which it is placed, it will sink. If the density is less, it will float. You can use math to calculate the density, if you know an object's mass and volume. Density is defined as mass divided by volume.


How do fish use density in order to move in the water?

Fish use density in order to move in the water since they do not have lungs. When the density of water keeps changing, fish use it to move and thereby using less energy.
