Density

Front

What is density?

Back

Density is the mass of an object divided by its volume. It tells us how much matter is packed into a certain space.

Front

What does it mean if an object floats in water?

Back

An object floats in water if it is less dense than water.

Front

What does it mean if an object sinks in water?

Back

An object sinks in water if it is more dense than water.

Front

How can you determine which liquid is the most dense when they do not mix?

Back

The most dense liquid will be at the bottom of the container.

Front

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

Back

Oil is less dense than water, which is why it floats on top.

Front

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

Back

A metal paper clip is more dense than water, which is why it sinks.

Front

What happens to the density of an object if you increase its volume but keep its mass the same?

Back

The density decreases because density is mass divided by volume.

Front

What is the relationship between density and buoyancy?

Back

Buoyancy is the ability of an object to float, which depends on the object's density compared to the fluid's density.

Front

If a sponge is placed in water, what can we conclude about its density?

Back

The sponge is less dense than water, which is why it floats.

Front

What is the density of water?

Back

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