(a)
Interpretation:
The reason for no change in volume of a piece of clay in water on changing the shape of the clay is to be explained.
Concept introduction:
Every matter is made of substance that has mass and volume. The material with which any matter is made of, decides the mass and volume of the object.
Answer to Problem 6E
The volume of the piece of clay does not change if the shape of clay is changed because the amount of material remains the same.
Explanation of Solution
On changing the shape of clay, only the thickness or length of the piece changes. There is no change in the material of clay or the piece submerged in water. Nothing is added or removed from the clay piece. Therefore, the volume remains the same as it displaces same amount of water on being completely submerged. Change of shape does not change the volume of a solid substance.
(b)
Interpretation:
Whether mass of a piece of clay in water will change or not on changing the shape of the clay is to be explained.
Concept introduction:
Every matter is made of substance that has mass and volume. The material with which any matter is made of, decides the mass and volume of the object.
Answer to Problem 6E
The mass of the piece of clay will not change on changing the shape of clay.
Explanation of Solution
The mass of the piece of clay will not change on changing the shape of clay as no new material is added or removed from the piece of clay. Since, the material remains same and it is submerged in same water, its mass will also remain same. Only the shape of clay is changed which does not change the volume of clay. So the mass will also remain same.
