Question

The volume of bag of mass 1250g is 150 cm^3 ..If this bag is put on water, will it float or sink... Justify your answer...

Answer 1

Explanation:

density of volume bag = 1250/150

=8.33 g/cm^3

density of water is 1 g/cm^3

as density of bag is greater than density of water, it will sink in it.

Answer 2

Given:

• Volume of bag = 150 cm³
• Mass of bag = 1250 g

To find:

• Will it float on water ?

Calculation:

First of all, calculate the density of the substance in the bag.

• Density is calculated as the mass divided by the volume of the object.

$\rho = \dfrac{mass}{volume}$

$\implies \: \rho = \dfrac{1250}{150}$

$\implies \: \rho = 8.33 \: g/ {cm}^{3}$

• Now, density of water is equal to 1 g/cm³.

• Now, an object has a density greater than the density of water, it sinks.

• This is because, the buoyant force provided by water on the bag will be lesser than the weight of the bag.

Hence, the bag will sink in water.
