HELLLPPP WLL MARK AND 5 STARS, USE RACE How does density affect the tendency of an object to float or sink in a liquid?

Explanation:

First you have to know the density of the liquid. The numbers range from 0.5  to about 2.

I the object you are putting into the liquid has a density greater than that of the liquid, then the object will sink (go below the surface of the liquid).

If the object has a density less than the liquid then the object will float.

If you take a chunk of solid iron, and put it water, there is no way that object is going to float (with one exception).  Iron has a density of about 8. Water is 1. Water is the standard.

If you put balsa wood in water there is no way it will sink. It has a density much less than almost all liquids.

So you do you make iron ships float? The answer to that is that ships are not solid. The shell of the ship has a volume much greater than the thickness of the hull of the ship. The density would be calculated as 8 / huge volume -- say 1,000,000 cubic cm.  (and that's not much of a volume.

The result is a density much less than 1. Iron ships really do float.

in a place once known as north america, now known as panem, is a very rich city surrounded by twelve districts. every year because this very rich city, known as the capitol, is so rich and likes to think they control all the districts - which they do - there is something known as the hunger games! this is where two children, one boy and one girl from each district from the ages of twelve to eighteen, have to leave their families and compete in the hunger games, a live event that is aired on tv's all over panem. when katniss everdeen, aged sixteen from district 12, has to volunteer to take the place of her twelve-year-old sister prim after prim's name is called forth to become the 23rd member to compete in the 74th hunger games, she promises to prim that she will win! katniss doesn't believe she's coming out alive - but she's not going down without a fight.

because district 12 is so poor, katniss has been close to death many times from starvation but she's made it through it. but this is a different kind of close to death; this katniss doesn't know if she can survive.

she doesn't want to hurt, or kill anyone but when it comes down to it katniss' instinct is to survive. but when she starts to have confusing feelings about the boy from her district who is also her fellow contender, things get worse, and then she teams up with the girl from district 11 and only one person can survive. but who will it be? will her feelings get the better of her? will she let someone else win so they don't have to die? if katniss is going to win she's going to have to be brutal. she's going to have to kill!

is there a passage to this question if so plz take a picture
