Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per cubic centimeter (g/cm³).

Front

What tool is used to measure mass?

Back

Triple beam balance.

Front

How does mass differ from weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 10 g and a volume of 2 cm³, what is its density?

Back

5 g/cm³.

Front

What happens to the density of an object if its mass increases but its volume stays the same?

Back

The density increases.

Front

Where can matter be found?

Back

Matter can be found everywhere.

Front

If a rock has a mass of 20 g and a volume of 5 cm³, what is its density?

Back

4 g/cm³.

Front

What is the density of water?

Back

1 g/cm³.

Front

How does the density of an object affect whether it will float or sink in water?

Back

Objects with a density less than 1 g/cm³ will float, while those with a density greater than 1 g/cm³ will sink.
