Measuring Matter- volume and density

Front

What is the definition of volume?

Back

Volume is the amount of space that an object occupies, typically measured in cubic units.

Front

What is the definition of density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per cubic centimeter (g/cm³).

Front

How do you find the volume of a rectangular box?

Back

The volume of a rectangular box is calculated using the formula: v = length x width x height (v = l x w x h).

Front

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

Back

The unit of measurement for volume in the metric system is cubic centimeters (cm³) or liters (L).

Front

What is the meniscus in a liquid measurement?

Back

The meniscus is the curve at the surface of a liquid in a container, and the level is read at the bottom of the meniscus.

Front

How do you calculate density?

Back

Density is calculated using the formula: Density = Mass / Volume.

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

What is the volume of a cube with a side length of 3 cm?

Back

Volume = side³ = 3 cm x 3 cm x 3 cm = 27 cm³.

Front

What happens to the density of an object if its mass increases but its volume remains the same?

Back

If the mass increases while the volume remains the same, the density of the object increases.

Front

What is the volume of a liquid in a graduated cylinder if the meniscus is at 50 mL?

Back

The volume of the liquid is 50 mL, read at the bottom of the meniscus.
