How is Matter Measured Test II

Front

What is volume?

Back

Volume is the amount of space that an object occupies, typically measured in liters (L) or cubic centimeters (cm³).

Front

How do you measure the volume of an irregular object?

Back

You can measure the volume of an irregular object by using the water displacement method. Submerge the object in a graduated cylinder filled with water and measure the change in water level.

Front

What is the formula for calculating the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated using the formula: Volume = length × width × height.

Front

What is 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 calculate density?

Back

Density is calculated using the formula: Density = mass/volume.

Front

What units are used to measure volume?

Back

Common units for measuring volume include milliliters (mL), liters (L), and cubic centimeters (cm³).

Front

What is the significance of a graduated cylinder?

Back

A graduated cylinder is a tool used to measure the volume of liquids accurately.

Front

If an object has a mass of 20g and a volume of 8cm³, what is its density?

Back

Density = mass/volume = 20g/8cm³ = 2.5g/cm³.

Front

What happens to the water level in a graduated cylinder when an object is submerged?

Back

The water level rises by an amount equal to the volume of the submerged object.

Front

What is the volume of a cube with a side length of 5 cm?

Back

Volume = side × side × side = 5 cm × 5 cm × 5 cm = 125 cm³.
