Read each question carefully and provide your answer in the space provided. Show all your calculations for problems.
1. Which of the following best defines density?
The amount of space an object occupies.
The mass per unit volume of a substance.
The weight of an object in a given volume.
The resistance of an object to deformation.
2. What are the standard SI units for density?
grams per liter (g/L)
kilograms per cubic meter (kg/m³)
pounds per cubic foot (lb/ft³)
grams per cubic centimeter (g/cm³)
3. The formula for density is mass divided by .
4. An object will float if its density is than the fluid it is placed in.
5. Archimedes' Principle states that the buoyant force on a submerged object is equal to the of the fluid displaced by the object.
6. A block of wood has a mass of 120 grams and a volume of 150 cm³. Calculate its density.
7. Explain why a hot air balloon floats, while a regular balloon filled with unheated air falls.
8. Density is an intensive property, meaning it does not depend on the amount of substance present.
True
False
9. A substance with a higher density will always have a greater mass than a substance with a lower density.
True
False
10. A metal cylinder has a radius of 2 cm and a height of 10 cm. If its mass is 942 grams, what is the density of the metal? (Use π = 3.14)
Observe the liquid tower below, which shows different liquids layered by density.
11. Based on the image, which liquid has the highest density? Explain your reasoning.
