Question

The volume ofa 500 g sealed packet is 350 cm³. Will the packet float or sink in water if the density of water is 1 g cm³? What will be the mass of the water displaced by this packet?

Answer 1

Answer:

The packet will sink in the water.

Mass of water displaced = 350 g.

Explanation:

In the question,

Mass of the sealed packet = 500 g

Volume of sealed packet, V = 350 cm³

Also,

Density of water = 1 g/cm³

As we know that,

$Density = \frac{Mass}{Volume}$

So,

Density of the sealed packet is given by,

$Density = \frac{500}{350}= 1.4285g/cm^{3}$

Therefore, as we can see that the density of the sealed packet is greater than the density of the liquid it is put into (i.e. water).

So,

We can say that the packet will sink inside the water.

Also,

The mass of the water displaced is equal to the volume of the sealed packet as it is fully immersed.

So,

Mass of water displaced = Volume of packet = 350 ml = 350 g (∵ density = 1 g/cm³).
