Practicing Measuring: Density Hands-On

What two quantities do you need to know find the density of a substance, material or object?

• mass

• volume

• length

• time

• temperature

Given the necessary quantities, how do you find the density of a substance, material or object?

• mass/volume

• volume/mass

• l x w x h

• πr2h

• volume x mass

What units are often used to express the volume of liquids?

• milliliters

• milligrams

• cubic centimeters

• deciliters

• decigrams

What units are often used to express the volume of solids?

• milliliters

• milligrams

• cubic centimeters

• deciliters

• decigrams

Which of the following units express equivalent volumes?

• milliliters

• ounces

• cubic centimeters

• cc

• teaspoons

Which of these are valid density units?

• kg/m3

• grams/milliliters

• grams/cc

• ml/g

• cm3/kg

Why is it important to consider temperature when problem-solving issues involving density?

• It isn't.

• Density varies with temperature.

• Warmer temperatures always cause mass to be lost.

• Warmer temperatures always cause mass to be gained.

What does “density is a characteristic property of substances” mean?

• Density for a given substance is always the same regardless of sample size.

• As the volume of a given substance changes the density of that substance changes.

• As the mass of a given substance changes the density of that substance changes.

The density of Object B is ___ g/cc? Do not round the volume calculation. Round the density calculation to the second decimal place.

The density of Object A is ___ g/cm3? Do not round the volume calculation. Round the density calculation to the second decimal place.
