Question

The volume of 500 gram sealed packet is 350cm cube . Will the packet float or sink in water if density of water is 1 gm/cm cube ? What will be the mass of water displaced by this packet ?

Answer 1

_/\_Hello mate__here is your answer--

_______________________

⭐ CONCEPT:-- If the density of an object is more than the density of a liquid, then it sinks in the liquid. On the other hand, if the density of an object is less than the density of a liquid, then it floats on the surface of the liquid.

________________________

Mass of packet, M = 500 g

Volume of packet,V = 350g/cm^3

Dencity of sealed packet =M/V

= 500 /350

= 1.428 g/cm^3

The density of the substance is more than the density of water (1 g/cm3). Hence, it will sink in water.

The mass of water displaced by the packet is equal to the volume of the packet, i.e., 350 g.

I hope, this will help you.☺

Thank you______❤

Answer 2

Given:

Volume of 500 gram sealed packet = 350cm³

Density of water = 1 gm/cm³

To find:

Will the packet float or sink in water if the density of water is 1 gm/cm³ and the mass of water displaced by this packet.

Solution:

We know that,

${Density = \frac{Mass}{Volume}} = \frac{500}{350} = 1.42 gm/cm^{3}$

The density of sealed packet > density of water, due to this the sealed packet will sink in water.

Now,

Mass of water displaced by the packet is equal to the volume of the packet times the density of water.

$m_{w} = \(\rho\)_{w} \times V = 1 \times 350 = 350 gm.$

Therefore, the mass of water displaced by this packet is 350gm.
