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 in water? Justify your answer


#1

Given m = 50 g,
V = 20 cm^3,
Density = ?,
Density of body = m /V
= 50/20
= 2.5 g cm^-3.
Since density of the body is greater than the density of water, therefore, the body will sink.
