Chapter 1, Problem 44R

To determine

Toexplain: The procedure to measure the volume, mass and density of a textbook, a container of milk and an air-filled balloon.

Explanation of Solution

Introduction:

Density is a ratio of mass to volume. The mean density of an object is the ratio of total mass to total volume. An object made from a material that is comparatively dense will have less volume than an object made of some less dense substance with equal mass.

Measurement of volume:

Volume of a book can be measured by multiplication of length, breadth and height $\text{l}\times \text{b}\times \text{h}$ , volume of milk container can be measured by measuring the amount of milk contained by the container and volume of the air filled balloon can be measured by measuring the amount of air occupied.

Measurement of mass:

The mass of a textbook, a container of milk and an air-filled balloon can be measured by weighing each with weighing machine.

Measurement of density:

The density of a textbook can be measured by dividing the mass of a textbook with its volume.

The density of a container of milk can be measured by dividing the mass of a container of milk with its volume.

The density of an air-filled balloon can be measured by dividing the mass of an air-filled balloon with its volume.

Conclusion:

Therefore, the mass, volume and density of given objects can be calculated using the formula of density.
