Physical and Chemical Properties and Changes

Front

What is solubility?

Back

Solubility is a physical property that describes the ability of a substance to dissolve in a solvent.

Front

What type of property is reactivity?

Back

Reactivity is a chemical property that indicates how a substance interacts with other substances.

Front

Define physical properties.

Back

Physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity.

Front

What is an example of a chemical change?

Back

Making toast is an example of a chemical change, as it involves a transformation of the bread into a different substance.

Front

What is viscosity?

Back

Viscosity is a physical property that measures a fluid's resistance to flow.

Front

What distinguishes physical changes from chemical changes?

Back

Physical changes do not alter the chemical identity of a substance, while chemical changes result in the formation of new substances.

Front

Give an example of a physical change.

Back

Melting ice is an example of a physical change, as it changes from solid to liquid without altering its chemical composition.

Front

What is the significance of boiling point in physical properties?

Back

Boiling point is a physical property that indicates the temperature at which a substance transitions from liquid to gas.

Front

How does temperature affect solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids, but can decrease the solubility of gases.

Front

What is a chemical property?

Back

A chemical property is a characteristic of a substance that becomes evident during a chemical reaction, indicating how it interacts with other substances.
