Front

What is relative density?

Back

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

Front

Why do rocks sink in water?

Back

Rocks sink because they are more dense than the water.

Front

What happens to liquids of different densities when poured together?

Back

Liquids of different densities will separate, with the most dense liquid at the bottom and the least dense liquid on top.

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.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.

Front

What is the formula for density?

Back

Density = Mass / Volume.

If a boat floats, what can we say about its density compared to water?

Back
