The volume of a 500 g sealed packet is \( 350 cm^3 \) . Will the packet float or sink in water if the density of water is \( 1 g/cm^3 \) ? What will be the mass of the water displaced by this packet?


Answer :

Density of sealed packet = \( \frac{500}{350} \ = \ 1.42 g/cm^3 \)

Density of sealed packet is greater than density of water

\(\therefore \) the packet will sink.

From Archimedes Principle, we know that

Displaced water volume = Force exerted on the sealed packet.

Volume of water displaced \( = 350 cm^3 \)

\(\Rightarrow \) displaced water mass = ? x V

\(\Rightarrow \) displaced water mass = 1 × 350

\(\therefore \) Mass of displaced water = 350g.
