Front

What is a chemical property?

Back

A chemical property is a characteristic of a substance that can only be observed during a chemical reaction, such as reactivity with air.

Front

Why is water less dense as a solid than as a liquid?

Back

Water's unique molecular structure causes it to expand when it freezes, allowing ice to float and insulating aquatic life.

Front

What is a liquid?

Back

A liquid is a state of matter that has a definite volume but takes the shape of its container.

Front

What is evaporation?

Back

Evaporation is the process by which liquid turns into vapor at temperatures below its boiling point.

Front

What is sublimation?

Back

Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the liquid phase.

Front

What is freezing?

Back

Freezing is the process of a liquid turning into a solid when its temperature is lowered.

Front

What is ionization?

Back

Ionization is the process of adding or removing electrons from an atom or molecule, resulting in the formation of ions.

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 chemical composition.
