Density Quiz

What is the formula for calculating density?

• Density = Volume / Mass.

• Density = Mass * Volume.

• Density = Mass / Volume

• Density = Mass + Volume.

A block of wood has a mass of 50 grams and a volume of 25 cubic centimeters. What is its density?

• 100 grams per cubic centimeter.

• 10 grams per cubic centimeter.

• 0.5 grams per cubic centimeter.

• 2 grams per cubic centimeter

Which of the following is an example of an observation?

• The sky is blue

• It is going to rain because it is getting dark out

• The sun is shining in a picture which means it is during the day

• The grass is green so it's probably summertime

Which of the following is an independent variable?

• The variable that is changed in an experiment

• The variable that remains constant in an experiment

• The variable that is being measured or observed in an experiment

• The variable that is forgotten about in an experiment

What is the independent variable in a graph showing how the change in temperature effects density?

• temperature

• pressure

• density

• time

If the mass of an object increases while its volume remains the same, what happens to its density?

• The density of the object cannot be determined.

• The density of the object remains the same.

• The density of the object increases.

• The density of the object decreases.

A liquid has a density of 0.8 g/mL. What is its mass if its volume is 100 mL?

• 80 g

• 0.5 g

• 200 g

• 0.1 g

What is the formula for calculating volume if density and mass are known?

• Volume = Mass / Density

• Volume = Mass * Density

• Volume = Density / Mass

• Volume = Density + Mass

If the volume of an object decreases while its mass remains the same, what happens to its density?

• The density of the object cannot be determined.

• The density of the object remains the same.

• The density of the object increases.

• The density of the object decreases.

A metal ball has a mass of 50 grams and a volume of 100 cubic centimeters. What is its density?

• 0.5 grams per cubic centimeter.

• 2 grams per cubic centimeter.

• 5 grams per cubic centimeter.

• 10 grams per cubic centimeter.
