Question

The volume of a solid of mass 500g is 350 cc

  1. What will be the density of the solid?
  2. What will be the mass of water displaced by this solid?
  3. What will be the relative density of the solid?
  4. Will it float or sink in water?

[Ans. (a) 1.42 g/cc (b) 350 g (c) 1.42 (d) it will sink in water]

Answer

Mass (m) = 500 g

Volume (V) = 350 cc

(a) Density = 500\over 350 = 1.42 g/cc

(b) The solid will displace water equal to its own volume.

The volume of water displace = 350 cc

Mass = volume × density

= 350 × 1 = 350 g

(c) Relative Density = 1.42\over 1 = 1.42

(d) Since the relative density of the solid (1.42) is greater than the relative density of water, therefore, the solid is heavier than water and hence it will sink in water.
