The volume Of 50 g of a substance is 20 cm^3. If the density of water is 1 g m^-3, will the substance float or sink in water ? Justify your answer


#1

The density of the body is given by
d = Mass/ Volume
= 50/20 = 2.5 g cm^-3.
Since density of the body is greater than water, therefore, the body will sink.
