Density Check-in Flashcard

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

If a substance has a mass of 14 grams and occupies a volume of 14 ml, what is its density?

Back

Density = 14 g / 14 ml = 1 g/ml.

Front

What happens to a helium balloon in air?

Back

A helium balloon rises in air because helium is less dense than air.

Front

What does it mean if two objects have equal volumes?

Back

It means they occupy the same amount of space, regardless of their mass.

Front

How do you read the measurement in a graduated cylinder?

Back

Your eyes should be at the level of the liquid to avoid parallax error.

Front

What is the relationship between mass and volume in determining density?

Back

Density increases with mass if the volume remains constant.

Front

What is the significance of a substance being less dense than another?

Back

A substance that is less dense will float on a denser substance.

Front

What is the difference between mass and weight?

Back

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