Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of water?

Back

The density of water is 1 g/cm³.

Front

Which substance has a density of 7.8 g/cm³?

Back

Iron.

Front

Does the density of an object change with its size?

Back

No, density is an intrinsic property and does not change with the amount of substance.

Front

What happens to objects with a density less than water?

Back

They float in water.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its identity, such as color, density, or malleability.

Front

What is malleability?

Back

Malleability is the ability of a substance to be deformed or shaped under pressure, often without breaking.

Front

What is the difference between physical and chemical properties?

Back

Physical properties can be observed without changing the substance, while chemical properties describe a substance's ability to undergo chemical changes.

Front

What is an example of a substance that would float in water?

Back

Cork.
