Question

define density of object which object will float and which object will sink explain by taking any five objects densities

Answer 1

density of an object is defined as the ratio of mass to its volume..D=m/V;
let's take example of stone,paper ball,wood,rubber,cloth.
stone will sink because it's density is more that is its molecules are more tightly packed...

Answer 2

If the density of an object will less than that of water or any liquid in which the object is submerged then the object will float. for example:

1. paper
2.wood
3.ship (as it has large volume so its density decreases)
4.air balloon
5.Thread


Now, If the density of an object will more than that of water or any other liquid in which the object is submerged then the object will sink. For example:

1. Iron block
2.Iron nail
3.when there is hole in a ship then the weight of the ship increases hence density increses so ship drowned into the water
4. Mobile phone
5. Stone
