Understanding Density, Relative Density, and Flotation

What is the order of liquids from top to bottom when honey, water, and kerosene are poured into a glass?

• Water, Honey, Kerosene

• Kerosene, Water, Honey

• Honey, Water, Kerosene

• Kerosene, Honey, Water

Which of the following best describes density?

• Mass per unit volume

• The color of a substance

• The weight of an object

• The volume of an object

What is the SI unit of density?

• Gram per centimeter cube

• Pound per inch cube

• Kilogram per meter cube

• Newton per meter

How is relative density calculated?

• Volume of substance divided by mass of water

• Density of substance divided by density of water

• Density of water divided by density of substance

• Mass of substance divided by volume of water

What is the relative density of a substance with a density of 1.4 g/cm³?

• 0.8

• 1.0

• 2.0

• 1.4

Which object will float in water based on its density?

• An object with density 3.0 g/cm³

• An object with density 2.0 g/cm³

• An object with density 1.5 g/cm³

• An object with density 0.5 g/cm³

Why does a steel nail sink in honey?

• Because its density is less than honey

• Because its density is equal to honey

• Because its density is greater than honey

• Because it is lighter than honey

What is the density range of a grape that sinks in water but floats on honey?

• Less than 0.8 g/cm³

• Between 0.8 and 1.0 g/cm³

• Between 1.0 and 1.4 g/cm³

• Greater than 1.4 g/cm³

What is the density of a plastic ball that floats on kerosene?

• Greater than 0.8 g/cm³

• Greater than 1.0 g/cm³

• Equal to 1.0 g/cm³

• Less than 0.8 g/cm³

How can a steel ship float on water despite steel's high density?

• The ship is filled with air

• The ship is coated with a floating material

• The ship is made of a special type of steel

• The ship is hollow, reducing its overall density
