Measurement: Mass & Volume

1. A piece of copper metal is correctly placed on a triple beam balance. The riders are all at the zero mark except for the rider on the 0-10 gram beam which is located at the position shown. What is the mass of the copper metal?

0.455g

4.56g

0.55g

5.50g

The mass of the copper metal is 5.50g because the rider on the 0-10 gram beam is located at the position shown, which indicates that it is weighing 5.50 grams.

Explanation

The mass of the copper metal is 5.50g because the rider on the 0-10 gram beam is located at the position shown, which indicates that it is weighing 5.50 grams.

2. A sphere was dropped into water in a graduated cylinder as shown. What is the volume of the sphere?

15 mL

25 mL

40 mL

65 mL

Explanation

3. The diagram below shows 3 graduated cylinders. The contents of cylinders X and Y are poured into cylinder Z. Which letter represents the amount of liquid that will be in container Z?

A

B

C

D

The diagram shows that cylinder X has a greater volume than cylinder Y, and when the contents of both cylinders are poured into cylinder Z, the liquid will take up the shape and volume of cylinder Z. Therefore, the correct answer is C, as it represents the amount of liquid that will be in container Z.

Explanation

The diagram shows that cylinder X has a greater volume than cylinder Y, and when the contents of both cylinders are poured into cylinder Z, the liquid will take up the shape and volume of cylinder Z. Therefore, the correct answer is C, as it represents the amount of liquid that will be in container Z.

4. The diagram below represents a portion of a triple-beam balance. What is the total mass?

540.20 g

540.52 g

545.20 g

545.52 g

The total mass is 545.20 g because the diagram shows that the left beam has a mass of 100 g, the center beam has a mass of 400 g, and the right beam has a mass of 45.20 g. Adding these masses together gives a total of 545.20 g.

Explanation

The total mass is 545.20 g because the diagram shows that the left beam has a mass of 100 g, the center beam has a mass of 400 g, and the right beam has a mass of 45.20 g. Adding these masses together gives a total of 545.20 g.

5. Which of the following statements best describes the difference between mass and volume?

Mass is a measure of an object's density, while volume is a measure of its weight.

Mass is the amount of space an object occupies, while volume is the quantity of matter in the object.

Mass and volume are equivalent terms and can be used interchangeably.

The main difference between mass and volume is that mass measures the quantity of matter in an object and is typically measured in units like kilograms or grams, while volume measures the space occupied by an object and is measured in cubic units like cubic meters or cubic centimeters. In essence, mass pertains to the amount of substance, whereas volume relates to the physical dimensions and space an object takes up.
