The volume of 50 g of a substance is 20 cm3. If the density of water is 1 g/cm3, will the substance float or sink?
A substance floats on water if its density is less than the density of water. A substance sinks in water if its density is more than the density of water.
Density of a substance > Density of water (substance sinks in water)
Density of a substance < Density of water (substance floats on water)
Volume = 20
Mass = 50g
Density of the given substance
Density of water
Here density of the given substance is more than the density of water. So the given substance will sink in water.
