Question

The volume of 800 g of a substance is
$2000 {cm}^{3}$
I) Will the substance float or sink In water?
ii) what will be the mass of water displaced by the substance? ​

Answer 1

Answer:

Explanation:

Given, mass of substance, m=50g;

volume, V=20cm  

3

; density, ρ=?

The density of substance given is  

d=  

V

m

​  

=  

20cm  

3

 

50g

​  

=2.5gcm  

−3

 

Hence the density of the substance is greater than the density of water. Hence the weight acting downwards Vdg is greater than the buoyant force acting upwards Vρ  

water

​  

g.

Hence the substance will sink in water.
