Density

What is the definition of density?

• The speed of light in a substance

• Amount of heat energy in a substance

• The force exerted by a substance

• Measure of mass per unit volume of a substance

How do you calculate density using mass and volume?

• Density = Mass * Volume

• Density = Mass - Volume

• Density = Mass / Volume

• Density = Volume / Mass

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

• 10 g/cm^3

• 2 g/cm^3

• 5 g/cm^3

• 25 g/cm^3

A block of wood has a mass of 120 grams and a volume of 60 cubic centimeters. What is its density?

• 180 grams per 30 cubic centimeters

• 0.5 grams per cubic centimeter

• 120 grams per 60 cubic centimeters

• 2 grams per cubic centimeter

If the density of a substance is 2 grams per cubic centimeter, what is its mass if the volume is 5 cubic centimeters?

• 3 grams

• 12 grams

• 10 grams

• 7 grams

If the density of a substance is 3 grams per cubic centimeter, what is its volume if the mass is 15 grams?

• 2 cubic centimeters

• 5 cubic centimeters

• 7 cubic centimeters

• 10 cubic centimeters

What happens to the density of an object if its mass stays the same but its volume increases?

• The density becomes negative

• The density remains the same

• The density decreases

• The density increases

If the density of an object is less than the density of water, what will happen when it is placed in water?

• It will turn into ice

• It will explode

• It will float

• It will sink

One edge of a cube is 5 cm and its mass is 500 gr. Calculate the density

• 4 gr/cm3

• 2 gr/cm3

• 1 gr/cm3

• 5 gr/cm3

r of a cylander is 2 cm and its height is 6 cm, its mass is 144 gr. find its density .(Pi is 3)

• 3 gr/cm3

• 4 gr/cm3

• 2 gr/cm3

• 5 gr/cm3
