Density of Liquids

Why do some substances float on water?

• they are warmer than water

• they are cooler than water

• they are more dense than water

• they are less dense than water

Why do objects sink or float in H₂O? 

• Because their densities are higher or lower than compared to water

• Because their densities are using gravity to pull down

• Because their densities are heavier or lighter

• Because their mass and volumes are equal 

floating or sinking when compared to water.

• volume

• solution

• relative density

• mixture

The water is ______ dense than the boat

• more

• less

A bobber floats on the water because it is....

• more dense than the water

• less dense than the water

• the same density as the water

• to show you when you have a bite

objects that are more dense than water will sink and objects that are less dense than water will float

• properties

• relative density

• physical state

• magnetism

Why does the egg not sink or float?

• it is more dense than the water

• it is less dense than the water

• it has the same density as the water

• it is light

What is the formula for density?

• density = mass x volume

• density = mass / volume

• density = mass + volume

• density = mass - volume

What is the density of a liquid if its mass is 200 grams and its volume is 250 milliliters?

• 0.8 g/mL

• 1.25 g/mL

• 0.5 g/mL

• 2 g/mL

Which instrument is commonly used to measure the density of a liquid?

• Thermometer

• Hydrometer

• Barometer

• Spectrometer
