7th 1.2 Measuring Matter

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of an object with a mass of 14g and a volume of 2cm³?

Back

7 g/cm³.

Front

What is the density of an object with a mass of 4g and a volume of 2cm³?

Back

2 g/cm³.

Front

What does it mean if an object is less dense than water?

Back

It will float.

Front

What does it mean if an object is more dense than water?

Back

It will sink.

Front

What tool is used to measure mass?

Back

Triple beam balance.

What is the volume of an object that has a mass of 10g and a density of 5 g/cm³?

Back

2 cm³.

Front

If an object has a density of 1 g/cm³, what will it do in water?

Back

It will float.

Front

What is the unit of measurement for density?

Back

g/cm³ (grams per cubic centimeter).
