Question

The Volume of 40 g of a substance is 20 cm ^3. The Density of water is 1g/cm^3. Will the substance sink or float ???

Please explain with steps

Answer 1

Answer:-

The substance will sink.

Explanation:-

→ Volume of the substance = 20cm³

→ Mass of the substance = 40g

Thus, density of the object (in g/cm³) is:-

=> Density = Mass / Volume

=> Density = 40g/20cm³

=> Density = 2 g/cm³

∵ 2 g/cm³ > 1 g/cm³

Since, density of the substance is greater than density of water, the substance will sink.

Some Extra Information:-

Relative density : Relative density is the density of the substance divided by the density of water at 1° C. R.D. is sometimes called specific gravity (sp. gr.)

• If the relative density of a solid or liquid is more than 1, then that substance will sink in water.

• If the relative density of a solid or liquid is less than 1, then that substance would float in water.
