6th Grade Density Review

Front

What is density?

Back

Density is defined as mass per unit volume, typically expressed in grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

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

Front

What are the units of measurement for density?

Back

The common units for density are grams per milliliter (g/mL) for liquids and grams per cubic centimeter (g/cm³) for solids.

Front

If a box has a mass of 20g and a volume of 4mL, what is its density?

Back

Density = Mass / Volume = 20g / 4mL = 5 g/mL.

Front

What is the density of a substance with a mass of 30g and a volume of 6 liters?

Back

The density is 5 g/L.

Front

Which lab tool is used to measure the volume of a liquid?

Back

A graduated cylinder is commonly used to measure the volume of liquids.

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

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

Front

What is the density of a rock that has a mass of 14g and a volume of 2cm³?

Back

The density of the rock is 7 g/cm³.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if its density is less than the density of the fluid.
