Density

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) or kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula for the volume of a rectangular prism?

Back

Volume = Length × Width × Height.

Front

If an object has a mass of 50g and a volume of 10cm³, what is its density?

Back

5 g/cm³.

Front

What is the unit of density in the metric system?

Back

g/cm³ (grams per cubic centimeter) or kg/m³ (kilograms per cubic meter).

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

What is the density of water?

Back

1 g/cm³ at 4°C.

Front

If a substance has a density less than 1 g/cm³, what will happen when placed in water?

Back

It will float.

Front

What is the relationship between mass, volume, and density?

Back

Density is a ratio of mass to volume; if mass increases while volume remains constant, density increases.

Front

How do you find the volume of an irregular object using water displacement?

Back

Submerge the object in water and measure the change in water level.
