Properties of Matter

Front

What is a chemical property?

Back

A characteristic of a substance that can only be observed during a chemical reaction, such as flammability or reactivity.

Front

What is a physical property?

Back

A characteristic of a substance that can be observed or measured without changing the substance's identity, such as color, density, or melting point.

Front

What is density?

Back

Density is the measure of how much mass is contained in a given volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is malleability?

Back

Malleability is the ability of a substance, usually a metal, to be hammered or pressed into thin sheets without breaking.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, such as salt dissolving in water.

Front

What happens during a physical change?

Back

During a physical change, some physical properties of a substance may change, but the substance retains its identity.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form or appearance of a substance without changing its identity, while a chemical change results in the formation of new substances.

Front

What is conductivity?

Back

Conductivity is the ability of a substance to conduct electricity or heat.

Front

What is the significance of boiling point?

Back

The boiling point is the temperature at which a liquid turns into vapor, indicating a physical property of the substance.

Front

What is the relationship between mass and volume in determining density?

Back

Density is calculated by dividing mass by volume (Density = Mass/Volume).
