Density Reading Questions Part 1

What property of an object causes it to feel heavy or light for its size?

• Volume

• Weight

• Mass

• Density

What is the formula for density?

• Density = mass / volume

• Density = mass + volume

• Density = mass x volume

• Density = volume / mass

Which of the following materials has the highest density?

• Copper

• Wood

• Plastic

• Aluminum

Why does a copper cube feel heavier than an aluminum cube of the same volume?

• All of the above

• Copper atoms are arranged differently than aluminum atoms

• Copper atoms are smaller than aluminum atoms

• Copper atoms have more mass than aluminum atoms

Which of the following statements is true?

• A sample of a substance with lower density always has a smaller volume

• A sample of a substance with higher density always has a smaller mass

• A small piece of iron weighs less than a larger piece of plastic

• A sample of lead weighs less than the same size sample of wax

What is the difference between mass and weight?

• Mass and weight are unrelated to each other

• Mass and weight are the same thing

• Mass is a measure of the amount of matter, weight is a measure of the force of gravity

• Mass is a measure of the force of gravity, weight is a measure of the amount of matter

Which of the following materials has the lowest density?

• Copper

• Plastic

• Aluminum

• Wood

How can you measure the mass of an object using a scale?

• The scale factors out the effect of gravity and displays only the mass

• The scale measures weight, not mass

• The scale measures both weight and mass

• The scale measures neither weight nor mass

Why is wood more similar in density to plastic than to copper?

• Wood is made of carbon, hydrogen, and oxygen atoms

• Wood is made of long molecules arranged and packed together

• Wood atoms are smaller and have less mass than copper atoms

• All of the above

What is the water displacement method used for?

• To measure the weight of an object

• To measure the mass of an object

• To measure the density of an object

• To measure the volume of an object
