Density Quiz

What is the formula to calculate the density of an object?

• Density = Volume / Mass

• Density = Mass / Volume

• Density = Mass + Volume

If an object has a mass of 50 grams and a volume of 10 cubic centimeters, what is its density?

Which of the following is NOT a unit of density?

What property of matter does density describe?

• The color of the matter

• The amount of matter in a given space

• The temperature of the matter

• The elasticity of the matter

If two objects have the same volume but different masses, what can be said about their densities?

• They have the same density.

• The object with the greater mass has a higher density.

• The object with the lesser mass has a higher density.

• Nothing can be said about their densities without knowing their specific volumes.

Why do objects with a lower density than water float?

• Because they are bigger

• Because they are lighter in color

• Because they displace a volume of water that weighs more than the object

• Because they are always made of plastic

What is true about the density of water as it gets COLDER than 0 degrees Celsius?

• It increases.

• It decreases.

• It stays the same.

• It becomes a liquid again.

How does temperature generally affect the density of solids?

• Increasing temperature always increases the density of solids.

• Increasing temperature always decreases the density of solids.

• Temperature has no effect on the density of solids.

• Increasing temperature usually decreases the density of solids, because solids expand when heated.
