Water Level
There is a boat in a pool, with a lead ball inside. If the ball will be thrown into the water, will the water level rise or fall?
When the ball is in the boat, it displaces the volume of water that is the same weight as the ball. If for example, the volume of the ball is 1 ml, its mass will be 11.3 grams, so it will have to displace 11.3 ml of water and thus the water level will rise. When the ball is in the water it displaces the water according to its volume, only (1 ml), so in this case the water level has fall.
