Chapter 3, Problem 40A

Which has more mass, a 2-kg fluffy pillow or a 3-kg small piece of iron? More volume? Why are your answers different?

To determine

The object that has more mass and more volume out of $2\text{-kg}$ fluffy pillow and a $3\text{-kg}$ small piece of iron.

Answer to Problem 40A

The $3\text{-kg}$ small piece of iron has more mass but a $2\text{-kg}$ fluffy pillow have more volume.

Explanation of Solution

Introduction:

The mass is the quantity of matter in an object while the volume is space taken up by the object.

Now, out of a $2\text{-kg}$ fluffy pillow and a $3\text{-kg}$ small piece of iron, the small piece of iron has more mass given as $3\text{-kg}$ . Whereas the space covered by the fluffy pillow is more as compared to the small piece of iron, hence it will have more volume as compared to the iron piece.

Conclusion:

The object having more mass differs from the object having more volume as these concepts are totally different. One of the mass depends on the amount matter contained in the object, while the other, volume, depends on the space covered by the object.
