• Meters cubed (m³)
• Grams (g)
• Gallons (gal)

How is density calculated?

• Mass multiplied by volume

If an object has a higher density than the fluid it's placed in, what will happen?

• It will float
• It will sink
• It will remain suspended
• It will dissolve

Which property describes a fluid's resistance to flow?

• Density

What happens to the density of an object if its mass increases but its volume remains the same?

• Density decreases
• Density increases
• Density remains the same
• Density becomes zero

Which method is used to determine the volume of an irregular object?

• Measuring with a ruler
• Water displacement
• Weighing on a balance
• Multiplying length, width, and height

If two objects have the same mass but different volumes, which one has a higher density?

• The object with the larger volume
• The object with the smaller volume
• Both have the same density
• It's impossible to determine
