Is solubility a chemical or physical property?

Back

Solubility is a physical property because it describes the ability of a substance to dissolve in a solvent without changing its chemical identity.

Front

Is flammability a chemical or physical property?

Back

Flammability is a chemical property because it describes a substance's ability to burn and undergo a chemical change.

Front

Is density a chemical or physical property?

Back

Density is a physical property, defined as mass per unit volume of a substance.

Is boiling point a chemical or physical property?

Back

Boiling point is a physical property, which is the temperature at which a substance changes from a liquid to a gas.

Front

What does it mean if a substance reacts with acid?

Back

If a substance reacts with acid, it indicates a chemical property, as it involves a chemical change and the formation of new substances.

Give an example of a chemical property.

Back

An example of a chemical property is rusting, which occurs when iron reacts with oxygen in the presence of moisture.

Front

What is the difference between physical and chemical properties?

Back

Physical properties can be observed without changing the substance's identity, while chemical properties can only be observed during a chemical reaction.
