Density, properties of matter, lava lamp flashcard

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).

Front

How is buoyancy defined?

Back

Buoyancy is the ability of an object to float in a fluid, determined by the object's density relative to the fluid's density.

Front

What happens during a chemical change?

Back

During a chemical change, a new substance is formed, which has different properties from the original substance.

Front

What is the relationship between density and floating?

Back

An object will float if its density is less than the density of the fluid it is in; it will sink if its density is greater.

Front

How do you calculate density?

Back

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

Front

What is the unit of measurement for density?

Back

The unit of measurement for density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

What is an example of a substance with high density?

Back

An example of a substance with high density is lead, which has a density of about 11.34 g/cm³.

Front

What is an example of a substance with low density?

Back

An example of a substance with low density is cork, which has a density of about 0.24 g/cm³.

Front

What is the principle of Archimedes?

Back

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

Front

What is the significance of the density of water?

Back

The density of water is approximately 1 g/cm³, which is used as a reference point for determining whether other substances will float or sink.
