Relative Density

Front

What is relative density?

Back

Relative density is a measure of how dense a substance is compared to the density of another substance, usually water.

What does it mean if an object floats in water?

Back

If an object floats in water, it means that it is less dense than water.

Front

What does it mean if an object sinks in water?

Back

If an object sinks in water, it means that it is more dense than water.

Front

How can you determine the order of density among different liquids?

Back

You can determine the order of density by observing which liquids float on top of others or by measuring their densities.

Front

What is the density of water?

Back

The density of water is approximately 1 gram per cubic centimeter (g/cm³).

Front

What happens to the density of a substance when it is heated?

Back

When a substance is heated, its density usually decreases because the particles move apart.

Front

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

Back

Oil is an example of a substance that is less dense than water and will float on it.

Front

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

Back

A rock is an example of a substance that is more dense than water and will sink.

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 compared to the fluid's density.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.
