Relative Density

Front

What is relative density?

Back

Relative density is a measure of how dense an object is compared to the density of water. It determines whether an object will float or sink in water.

Front

What happens to objects that are more dense than water?

Back

Objects that are more dense than water will sink.

Front

What happens to objects that are less dense than water?

Back

Objects that are less dense than water will float.

Front

How can you determine which of three non-mixing liquids is the most dense?

Back

The most dense liquid will be at the bottom when the liquids are poured into a container.

Front

If you have four liquids, how do you order them from most dense to least dense?

Back

You compare their densities and arrange them accordingly, with the most dense at the top and the least dense at the bottom.

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 relative to the fluid's density.

Front

What is an example of a dense object that sinks in water?

Back

A rock is an example of a dense object that sinks in water because it is more dense than water.

Front

What is an example of a less dense object that floats in water?

Back

A piece of wood is an example of a less dense object that floats in water because it is less dense than water.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the unit of measurement for density?

Back

The unit of measurement for density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
