Question

give four steps of procedure to set up an experiment of to establish the relationship between the loss of weight of solid when fully immersed in tap water, salty water and weight of water displaced by it. please help me

Answer 1

 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 forcesThe weight of the block.The downward thrust due to pressure of the liquid on the upper surface of the block. Upward forcesThe 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.
