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 reference substance, usually water.

Front

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

Back

An object will float if its relative density is less than 1 (less dense than water) and sink if its relative density is greater than 1 (more dense than water).

Front

What is the relative density of water?

Back

The relative density of water is 1.

Front

If an object has a relative density of 0.8, what will happen when placed in water?

Back

The object will float because it is less dense than water.

Front

If an object has a relative density of 1.2, what will happen when placed in water?

Back

The object will sink because it is more dense than water.

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.

Front

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

Back

Sand is an example of a substance that is more dense than water.

Front

What happens to the relative density of an object if it is cut in half?

Back

The relative density remains the same regardless of the size of the object.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the relationship between mass, volume, and density?

Back

Density is the ratio of mass to volume; as mass increases with constant volume, density increases.
