When an object is submerged (below the surface) in water, When an object is submerged (below the surface) in water, the object displaces the amount of water equal to the the object displaces the amount of water equal to the objects volume. This means that the object pushes the objects volume. This means that the object pushes the water out of its way. This causes the surface of the water water out of its way. This causes the surface of the water to rise; you have displaced water with your body.to rise; you have displaced water with your body.

A graduated cylinder is filled with 50 ml of water. After placing a stone A graduated cylinder is filled with 50 ml of water. After placing a stone

in the cylinder, the water level is 63 ml. What is the volume of the in the cylinder, the water level is 63 ml. What is the volume of the

stone?stone?

The amount of water displaced equals the volume of the rock.The amount of water displaced equals the volume of the rock. The volume of the rock equal the amount the water level rises.The volume of the rock equal the amount the water level rises. How can the rise of the water level be calculated? Determine the How can the rise of the water level be calculated? Determine the

difference between the two water levels.difference between the two water levels.

Water level with the rock = 63 mlWater level with the rock = 63 ml

Water level without the rock= 50 mlWater level without the rock= 50 ml

Difference between the two water levels = 63 ml – 50 ml = 13 mlDifference between the two water levels = 63 ml – 50 ml = 13 ml

Answer: The volume of the rock is 13 mlAnswer: The volume of the rock is 13 ml
