Relative Density

Front

What is relative density?

Back

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

Front

What happens when the weight of an object is greater than the buoyant force?

Back

The object will sink.

Front

How do you calculate density?

Back

Density is calculated by dividing mass by volume (Density = Mass/Volume).

Front

If an object has a mass of 4 g and a volume of 2 cm³, what is its density?

Back

2 g/cm³.

Front

What is the metric unit used to measure small volumes of liquid?

Back

Milliliter (mL).

Front

What determines whether an object sinks or floats in a fluid?

Back

An object will sink if it is denser than the fluid and float if it is less dense.

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What is the relationship between density and buoyancy?

Back

An object's buoyancy is determined by its density relative to the fluid it is in.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

Front

What does it mean if an object has the same density as water?

Back

It means the object will neither sink nor float; it will remain suspended in the water.
