Density Worksheet

Name__________________________ Period: _____

1.Define mass?

2.Define volume?

3.Define density and show the formula for calculating density.

4.Why does changing the shape of an object have no effect on the density of that object?

5.Aluminum is used to make airplanes. Cast iron is used to make weightlifting equipment. Explain why the densities of these metals make them useful for these purposes?

6.What is the density of water? Remember for water 1g=1ml=1cm3

7.Why does an air bubble rise to the surface of a glass of water?

8. Calculate the densities of the following objects. Remember to place units after each number.

Object A: length = 6cm width = 3cm height = 1cm mass = 36g

volume = ____________ density = ______________

Object B: length = 10cm width = 5cm height = 2cm mass = 300g

volume = ____________ density = ________________

Object C: Use the water displacement method to determine the density of object C (silly putty).

initial water level in graduated cylinder = 25ml

final water level after placing silly putty into graduated cylinder = 29ml

mass of silly putty=8g

volume = _____________ density = ____________

9. Which of the following materials will float on water (density 1 g/ml)?

air = .001 g/cm3

corn oil = .93 g/cm3

glycerine = 1.26 g/cm3

corn syrup = 1.38 g/cm3

wood = .85 g/cm3

steel = 7.81 g/cm3

rubber = 1.34 g/cm3

ice = .92 g/cm3

water = 1.00 g/cm3

10. Assuming the materials don’t mix, show how the materials in question (9) would "stack up" in a graduated cylinder.
