Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following statements accurately defines density?
The amount of space an object occupies.
The force exerted by gravity on an object.
The amount of mass per unit volume.
The ability of an object to float.
2. A block of wood has a mass of 120 grams and a volume of 150 cm³. What is its density?
0.8 g/cm³
1.25 g/cm³
30 g/cm³
270 g/cm³
1. Density is an property of matter, meaning it does not depend on the amount of substance present.
2. When an object is placed in a fluid, it will if its density is less than the fluid's density.
3. The SI unit for density is .
1. Explain how temperature affects the density of most substances.
2. Describe a real-world application where understanding density is crucial.
1. A denser object will always sink in water.
True
False
2. The density of a substance changes if you break it into smaller pieces.
True
False
Observe the image below, which depicts a density tower experiment. Different liquids are layered based on their densities.
1. Based on the image, identify the characteristic that determines the order of the liquids in the tower.
2. If you were to add a small plastic bead (density = 1.05 g/cm³) to this tower, where would you expect it to settle?
