Density Quiz

What does density measure?

• The color of an object

• The amount of space an object takes up

• How much "stuff" is packed into a space

• The temperature of an object

What is the formula for calculating density?

• d = V/m

• d = m/V

• d = m + V

• d = V - m

Why does oil float on water?

• Oil is heavier than water

• Oil has a higher density than water

• Oil has a lower density than water

• Oil is colder than water

What are the units for density?

• Grams per liter (g/L)

• Use a scale and subtract the container's mass

• Use a ruler

• Use a calculator

What unit is used to write down the mass?

• Liters (L)

• Grams (g)

• Meters (m)
