Relative Density

Front

What is relative density?

Back

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

Front

Why does a bobber float on water?

Back

A bobber floats on water because it is less dense than the water.

Front

What happens to an object with a density greater than water?

Back

An object with a density greater than water will sink.

Front

What happens to an object with a density less than water?

Back

An object with a density less than water will float.

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 its density relative to the fluid.

Front

If an object has the same density as water, what will it do?

Back

If an object has the same density as water, it will neither sink nor float; it will remain suspended.

Front

How do you determine if an object will float or sink?

Back

You determine if an object will float or sink by comparing its density to the density of the fluid.

Front

What is the formula for density?

Back

Density = Mass / Volume.

Front

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

Back

Oil is an example of a liquid that is less dense than water.

Front

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

Back

Mercury is an example of a liquid that is more dense than water.
