The volume of 50 g of a substance is 20 `cm^3`. If the density of water is `1(g)/(cm^3)`, will the substance float or sink?

Answer

the substance will sink.

Explanation

If the density of an object is more than the density of a liquid then it sinks in the liquid On the other hand if the density of an object is less than the density ofa liquid then it floats on the surface of the liquid.
Here, density of the substance =Mass of the substance/Volume of the substance
=50/20
`=2.5gcm^(-3)`
The density of the substance is more than the density of water (`1 g cm^(-3)`). Hence the substance will sink in water.
