Q

# 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?

Q. 22.     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? What will be the mass of the water displaced by this packet?

Mass of the packet = 500 g

Volume of the packet = 350 cm3

Density of the packet is given by

$\\\rho =\frac{500}{350}\\ \rho =1.428\ cm^{3}$

As the density of the packet is less than that of water it will sink in water.

Volume of the water displaced by the packet = volume of the packet = 350 cm3

Mass of the water displaced by the packet = Volume of the water displaced by the packet X Density of water

= 350 X 1

= 350 g

Mass of water displaced is less than the mass of packet, so the packet will sink.
