Exploring Density and Buoyancy Concepts

What is the formula for density?

• Density = Mass + Volume

• Density = Mass / Volume

• Density = Volume / Mass

• Density = Mass \times Volume

If an object has a mass of 10 kg and a volume of 2 m³, what is its density?

• 5 kg/m³

• 20 kg/m³

• 0.2 kg/m³

• 12 kg/m³

Which of the following units is used to measure mass?

• Liters

• Meters

• Kilograms

• Newtons

An object with a density greater than water will:

• Float

• Sink

• Neither sink nor float

• Dissolve

What is the volume of an object with a mass of 24 kg and a density of 3 kg/m³?

• 8 m³

• 72 m³

• 12 m³

• 6 m³

Which of the following is a property of matter that describes the amount of space it occupies?

• Mass

• Volume

• Density

• Weight

Which of the following is NOT a factor that affects whether an object will sink or float?

• Density of the object

• Volume of the object

• Color of the object

• Density of the fluid

If an object floats in water, what can be said about its density compared to water?

• It is greater than the density of water

• It is less than the density of water

• It is equal to the density of water

• It is unrelated to the density of water

What is the mass of an object with a density of 4 kg/m³ and a volume of 3 m³?

• 12 kg

• 7 kg

• 1.33 kg

• 4 kg

Which of the following best describes the concept of mass?

• The amount of space an object occupies

• The amount of matter in an object

• The force exerted by gravity on an object

• The ability of an object to float
