The iron ball has a greater density than water so the gravitational force applied is greater on it than the buoyant force. Hence, it sinks. Whereas, a rubber ball has a lesser density than water. So, the opposing buoyant force is greater and since the ball floats.
Does an iron ball float in water?
(a) The ball will float. It is because the density of the iron ball is lesser than the density of mercury.
Why does an iron ball sinks in water?
Answer: Solution: The density of iron is more than the density of water, so the weight of iron is more than weight of water displaced by it and nail sinks. While the shape of an iron ship is made in such a way that it displaces more weight of water than its own weight.
Which ball can float on water?
Objects float due to the difference in densities, and anything that is light will be pushed upwards by the force of water. Tennis ball weighs much lighter and, therefore, cannot sink. The buoyant force makes them float at the top.
Can you think of a way to make iron float on water?
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.
26 related questions foundDo all objects that sink in water sink in oil give reason?
1 No all objects that sink in water don't sink in oil. 2 Oil is less dense than water as it floats on the surface of anybody of water. 3 Due to the differences in the density of water and oil some objects which sink in water may float in oil.
Where do you observe Archimedes principle in daily life give two examples?
1. On entering a bathtub filled with water, an equal quantity of water is displaced as the weight of the person. 2. A ship floats in the sea because of the buoyant force acting from the water.
Can a steel ball float?
The density of the steel balls is greater than the density of the water so they float in water. When the steel balls are placed in mercury then it floats in it because the density of the mercury is greater than the density of the steel balls. So, the steel balls displace the water equal to their weight and hence float.
Can a metal ball sink in water?
(i) A steel ball sinks in water because density of steel ball is greater than that of water.
Why does iron ball floats on mercury but sinks in water?
Detailed Solution. As can be seen, the density of iron is less than that of mercury but greater than water, therefore, it floats in mercury but sinks in water.
Why is ice floats on water?
Believe it or not, ice is actually about 9% less dense than water. Since the water is heavier, it displaces the lighter ice, causing the ice to float to the top.
Why does iron sink in water but float on mercury?
The density of mercury higher than iron, while the density of iron is higher than water. Therefore, iron floats in mercury, but sinks in water.
How does a metal ship float on water?
The answer to why ships can float comes from the famous principle of Archimedes which says that the net upward force on an object immersed in water is equal to the weight of the water displaced by the object.
Why do boats float on water?
The air that is inside a ship is much less dense than water. That's what keeps it floating! The average density of the total volume of the ship and everything inside of it (including the air) must be less than the same volume of water.
Can a ball float on water?
Although the bubble wrap makes the ball weigh a little more, it also displaces extra water making the ball more buoyant. The pockets of air in the bubble wrap mean that the ball and bubble wrap together are less dense than the water, which means the ball floats!
Does glass ball sink or float in water?
This is because glass can be created in several different ways, and the density of the final product depends on the densities of the individual starting products. However, it is common knowledge that steel is more dense than all forms of glass. Therefore, the glass ball will float in all of the substances named above.
Can stainless steel float on water?
Stainless steel is also a lighter material than copper, where buoyancy is an important factor and offers exceptional resistance to corrosion. The most common types of types or types of stainless steel are grades 304 and 316.
Will a hollow metal ball float?
Now, if you take a sphere, the metal outside of the sphere will be much heavier than the water, but because it hasn't got anything in it, that doesn't contribute to the density. So its average density be quite low. So it will float.
Why does solid steel ball float on the surface of mercury?
The correct answer is The density of mercury is higher than that of steel.
What is Archimedes Principle give example?
General Science
The force exerted by fluid on a solid body immersed must partially or completely in it is called the force of buoyancy, buoyant force or simply buoyancy. Example, a ship floats on water due to the Archimedes principle. mitgliedd1 and 88 more users found this answer helpful.
Which of the following phenomena can be explained using Archimedes Principle?
Archimedes' principle allows the buoyancy of any floating object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight. The upward, or buoyant, force on the object is that stated by Archimedes' principle, above.
How is Archimedes Principle used today?
It was originally used to empty sea water from a ship's hull. It is still used today as a method of irrigation in developing countries, according to the Archimedes Palimpsest.
Will object float better in oil or in water?
Oil. Oil is less dense than water, and so floats on top of it.
