Relative Density

Front

What is relative density?

Back

Relative density is the ratio of the density of a substance to the density of a reference substance, typically water for liquids and air for gases.

Front

How is relative density calculated?

Back

Relative density is calculated using the formula: Relative Density = Density of Substance / Density of Reference Substance.

Front

What does a relative density greater than 1 indicate?

Back

A relative density greater than 1 indicates that the substance is denser than the reference substance and will sink in it.

Front

What does a relative density less than 1 indicate?

Back

A relative density less than 1 indicates that the substance is less dense than the reference substance and will float in it.

Front

What is the significance of relative density in buoyancy?

Back

Relative density helps determine whether an object will float or sink in a fluid, which is essential for understanding buoyancy.

Front

What is the reference substance for measuring the relative density of liquids?

Back

The reference substance for measuring the relative density of liquids is typically water.

Front

What is the reference substance for measuring the relative density of gases?

Back

The reference substance for measuring the relative density of gases is typically air.

Front

How does temperature affect the relative density of a substance?

Back

Temperature can affect the density of a substance; as temperature increases, density usually decreases, which can alter the relative density.

Front

What is the relationship between relative density and specific gravity?

Back

Relative density is often referred to as specific gravity, and they are used interchangeably in many contexts.

Front

Can relative density be used to identify substances?

Back

Yes, relative density can be used as a property to help identify substances, as different materials have characteristic relative densities.
