What is Density?

In simple terms, what is density?

• How compact/pressed together an object is

• The amount of space something takes up

• How much matter is in an object

• The distance between two points

If the density of an object is less than the density of water, will it FLOAT or SINK?

• FLOAT

• SINK

What is the formula for density?

• d = (m) (v)

• d = m/v

• d = v/m

• d = mv²

What is the formula for mass?

• m = (d) (v)

• m = d/v

• m = v/d

• m = d/v²

What is the formula for volume?

• v = d/m

• v = (m) (d)

• v = m/d

• v = d/m²

A liquid with a density of 0.8 g/mL is poured into water (density 1 g/mL). Where will the liquid settle?

• On top of the water

• Below the water

• Mixes evenly with water

• It will evaporate

A heart-shaped object has a density of 1.5 g/cm³. Will it FLOAT or SINK in water?

• FLOAT

• SINK

If the mass of an object is doubled but the volume stays the same, what happens to its density?

• It doubles

• It halves

• It stays the same

• It becomes zero
