Question

1. Can you make iron to float in water? How? (AS)
2. Where do you observe Archimedes principle in daily life? Give two examples.(AS
3. Do all objects that sink in water, sink in oil? Give reason. (AS)
​

Answer 1

Answer:

1. Yes, this is by making its density lower than that of water. This you can do by making the iron assume a hollow shape. The shape would cause the iron to displace water equal to its weight and float.with the density higher than that of the iron.

2. (I) On entering a bathtub filled with water, an equal quantity of water is displaced as the weight of the person

(II) A ship floats in the sea because of the buoyant force acting from the water

3. No, all objects that sink in water, don't sink in oil. Oil is less dense than water as it floats on the surface of anybody of water. ... The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is immersed in
