Measurement and 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 units are used to measure mass?

Back

Mass is commonly measured in grams (g) or kilograms (kg).

Front

What units are used to measure volume?

Back

Volume is measured in milliliters (mL) or cubic centimeters (cm³).

Front

If Block A has a mass of 8 grams and a volume of 4 mL, what is its density?

Back

Density = Mass / Volume = 8g / 4mL = 2 g/mL.

Front

If Block B has a mass of 4 grams and a volume of 2 mL, how does its density compare to Block A?

Back

Block B's density is 2 g/mL, which is equal to Block A's density.

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

The density of the object increases.

Front

What happens to the density of an object if its volume increases while its mass remains constant?

Back

The density of the object decreases.

Front

How can you determine if an object will float or sink in water?

Back

An object will float if its density is less than that of water (1 g/mL) and sink if its density is greater.

Front

What is the relationship between mass and volume in terms of density?

Back

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