CHEM U3 Test Review #3 (Phases & Phase Changes)

Front

What is condensation?

Back

Condensation is the phase change from gas to liquid, occurring when gas particles lose energy and come together to form a liquid.

Front

What is sublimation?

Back

Sublimation is the phase change from solid to gas without passing through the liquid phase, often seen in dry ice.

Front

What is deionization?

Back

Deionization is the process of removing ions from a substance, typically referring to the conversion of a gas to a plasma state.

Front

What is deposition?

Back

Deposition is the phase change from gas to solid without passing through the liquid phase, such as frost forming on a cold surface.

Front

What is the gas phase?

Back

The gas phase is one of the states of matter where particles are far apart and move freely, allowing gases to fill their container.

Front

What is vaporization?

Back

Vaporization is the phase change from liquid to gas, which can occur through boiling or evaporation.

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 evaporation?

Back

Evaporation is the process by which molecules at the surface of a liquid gain enough energy to enter the gas phase.

Front

What is the plasma phase?

Back

The plasma phase is a state of matter where gas is energized to the point that some electrons break free from atoms, creating a mixture of charged particles.

Front

What is a Bose-Einstein Condensate?

Back

A Bose-Einstein Condensate is a state of matter formed at temperatures close to absolute zero, where a group of atoms behaves as a single quantum entity.
