Density practice 2

Front

What is density?

Back

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

Front

How do you determine which object is denser?

Back

To determine which object is denser, compare their mass and volume. The object with a higher mass for the same volume is denser.

Front

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

Back

Objects with a density greater than water (1 g/cm³) will sink.

Front

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

Back

Objects with a density less than water will float.

Front

If two liquids do not mix, how can you tell which is denser?

Back

The denser liquid will settle at the bottom, while the less dense liquid will float on top.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

Front

Which is denser: gold (19.3 g/cm³) or lead (11.4 g/cm³)?

Back

Gold is denser than lead.

Front

What is the relationship between density and buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the object's density relative to the fluid's density.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 30 g and a volume of 10 cm³, what is its density?

Back

Density = 30 g / 10 cm³ = 3 g/cm³.
