Density

What happens to objects with a density greater than water when placed in water?

• They float.

• They dissolve.

• They sink.

• They remain suspended.

What happens to objects with a density less than water when placed in water?

• They sink.

• They float.

• They dissolve.

• They break apart.

Why do some substances float on water?

• They are less dense than water.

• They are more dense than water.

• They are heavier than water.

• They are lighter than air.

If a brick sinks in water, what can you infer about its density compared to water?

• The brick has a lower density than water.

• The brick has the same density as water.

• The brick has a higher density than water.

• The brick's density is unpredictable.

What is an example of a substance that is less dense than water?

• Oil

• Mercury

• Water

• Honey

How do you calculate density?

• Density = Mass + Volume.

• Density = Mass - Volume.

• Density = Mass / Volume.

• Density = Volume / Mass.

What is density?

• Density is the mass of an object divided by its volume, usually expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

• Density is the volume of an object divided by its mass, usually expressed in liters per cubic meter (L/m³).

• Density is the weight of an object divided by its surface area, usually expressed in kilograms per square meter (kg/m²).

• Density is the mass of an object multiplied by its volume, usually expressed in grams per cubic meter (g/m³).

If an object has a mass of 10g and a volume of 5cm³, what is its density?

• 1 g/cm³

• 2 g/cm³

• 3 g/cm³

• 4 g/cm³

What is an example of a substance that is more dense than water?

• A metal like iron

• Wood

• Ice

• Oil

If an object has a density of 0.8 g/mL, will it sink or float in water?

• It will sink.

• It will float.

• It will neither sink nor float.

• It will dissolve in water.
