to verify archimedes' principle
Answers
Tap water
Strong salty water
This can be done by using at least two different solids in the experiment.
The Theory
When a metallic block is immersed in water (or any other liquid), four vertical forces act upon the block below the surface of water. These forces can be grouped into two types of forces.
Downward forces
The weight of the block.
The downward thrust due to pressure of the liquid on the upper surface of the block.
Upward forces
The tension of the spring, which measures the apparent weight.
The upward thrust due to liquid present below the lower surface of the block. This upward thrust is known as Buoyancy.
What happens to the weight of a body when immersed in water?
The more a body is immersed in water, the more the weight of the body decreases. The weight of the body is least when it is completely immersed in water. This means that loss in weight of the body increases as it is completely immersed in water.
When a body is partly or completely immersed in water (or any other liquid), then:
Loss in weight of body = Weight of water (liquid) displaced by the body = Buoyant force or upthrust exerted by water (any liquid) on the body.
It was Archimedes who first observed that bodies lose their weight when immersed in water. He proposed a principle based on his observation that is now known as the Archimedes' Principle.
What does Archimedes' Principle state?
The Principle states that: “A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.”
Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”
Thus, when a solid is fully immersed in a liquid, it loses weight which is equal to the weight of the liquid it displaces.

Answer:
Archimedes’ principle states: An object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid. Thus, the objective of underwater vehicle flotation systems is to counteract the negative buoyancy effect of heavier than water materials on the submersible (frame, pressure housings, etc.) with lighter than water materials; A near neutrally buoyant state is the goal. The flotation foam should maintain its form and resistance to water pressure at the anticipated operating depth. The most common underwater vehicle flotation materials encompass two broad categories: Rigid polyurethane foam and syntactic foam.
The term ‘rigid polyurethane foam’ comprises two polymer types: Polyisocyanurate formulations and polyurethane formulas. There are distinct differences between the two, both in the manner in which they are produced and in their ultimate performance.
Polyisocyanurate foams (or ‘trimer foams’) are generally low-density, insulation-grade foams, usually made in large blocks via a continuous extrusion process. These blocks are then put through cutting machines to make sheets and other shapes. ROV manufacturers generally cut, shape, and sand these inexpensive foams, then coat them with either a fibreglass covering or a thick layer of paint to help with abrasion and water intrusion resistance. These resilient foam blocks have been tested to depths of 1000 feet of seawater (fsw) (305 m) and have proven to be an inexpensive and effective flotation system for shallow water applications
Explanation:
When a metallic block is immersed in water (or any other liquid), four vertical forces act upon the block below the surface of water. These forces can be grouped into two types of forces.
Downward forces
The weight of the block.
The downward thrust due to pressure of the liquid on the upper surface of the block.

The upward thrust due to liquid present below the lower surface of the block. This upward thrust is known as Buoyancy.
What happens to the weight of a body when immersed in water?
The more a body is immersed in water, the more the weight of the body decreases. The weight of the body is least when it is completely immersed in water. This means that loss in weight of the body increases as it is completely immersed in water.
When a body is partly or completely immersed in water (or any other liquid), then:
Loss in weight of body = Weight of water (liquid) displaced by the body = Buoyant force or upthrust exerted by water (any liquid) on the body.
It was Archimedes who first observed that bodies lose their weight when immersed in water. He proposed a principle based on his observation that is now known as the Archimedes' Principle.
What does Archimedes' Principle state?
The Principle states that: “A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.”
Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”
Thus, when a solid is fully immersed in a liquid, it loses weight which is equal to the weight of the liquid it displaces.
The more the density of liquid in which the solid is immersed, the less is the weight of the liquid displaced on immersing the solid.
Does a body float?
Some bodies, if dropped in water, sink, such as a stone or a metallic needle. On the other hand, some bodies, even of the same weight as that of those that sink, float on water. This can be proved through the Laws of Flotation.
What does the Law of Flotation state?
A body will float if the weight of the body is equal to the weight of the liquid displaced.
If the weight of the immersed body is more than the weight of the water displaced, the body will sink.
Learning outcomes
The results obtained confirm Archimedes' Principle. They prove that:
When a body is partly or completely immersed in water, it loses weight.
A body loses its maximum weight when it is completely immersed in water.
When a body is partly or completely in water then:
Loss in weight of the body = Weight of water displaced by the body = Buoyant Force or up-thrust exerted by water on the body.
Volume of the water displaced = Volume of the body immersed in water.
