Density Flashcardzi Practice 1

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

How do you calculate the mass of a substance given its volume and density?

Back

Mass = Density × Volume.

Front

What is the density of pure water at room temperature?

Back

The density of pure water at room temperature is approximately 1 g/cm³.

Front

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

Back

Density is a measure of how much mass is contained in a given volume. If the mass increases while the volume remains constant, density increases.

Front

What tool is best for measuring the volume of a liquid accurately?

Back

A graduated cylinder is the best tool for measuring the volume of a liquid accurately.

Front

Why does an inflated balloon float in water?

Back

An inflated balloon floats in water because it is less dense than the water.

Front

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

Back

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

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which depends on the object's density compared to the fluid's density.

Front

How does a submarine control its buoyancy?

Back

A submarine controls its buoyancy by adjusting its mass through taking in or expelling water.

Front

What is the principle of Archimedes?

Back

The principle of Archimedes states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object.
