Calculating Density Practice

Front

What is the formula for calculating density?

Back

Density (D) is calculated using the formula D = m/v, where m is mass and v is volume.

Front

If an object has a mass of 20 grams and a volume of 5 cm³, what is its density?

Back

The density is 4 g/cm³ (D = 20g / 5cm³).

Front

What is the unit of measurement for density in the metric system?

Back

The unit of measurement for density in the metric system is grams per cubic centimeter (g/cm³).

Front

How does increasing the mass of an object affect its density if the volume remains constant?

Back

If the mass increases while the volume remains constant, the density increases.

Front

How does increasing the volume of an object affect its density if the mass remains constant?

Back

If the volume increases while the mass remains constant, the density decreases.

Front

What is the density of water at 4°C?

Back

The density of water at 4°C is approximately 1 g/cm³.

Front

What does it mean if an object has a density less than that of water?

Back

If an object has a density less than that of water (1 g/cm³), it will float.

Front

What does it mean if an object has a density greater than that of water?

Back

If an object has a density greater than that of water (1 g/cm³), it will sink.

Front

How can you determine the volume of an irregularly shaped object using water displacement?

Back

You can determine the volume of an irregularly shaped object by measuring the amount of water displaced when the object is submerged.

Front

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

Back

The relationship is defined by the formula D = m/v, indicating that density is the ratio of mass to volume.
