LT 1&2 Phases of Matter Review

Front

What are the phases of matter?

Back

The phases of matter are solid, liquid, gas, and plasma, which describe the physical states of a substance based on temperature and pressure.

What does a phase change diagram represent?

Back

A phase change diagram visually represents the changes in state of a substance as it undergoes heating or cooling, showing the relationship between temperature and phase.

What does the diagonal line on a phase change diagram indicate?

Back

The diagonal line indicates a change in temperature, where the substance is either heating up or cooling down.

What does the flat line on a phase change diagram indicate?

Back

The flat line indicates a phase change, where the temperature remains constant while the substance transitions from one phase to another.

What happens to molecules during melting?

Back

During melting, molecules absorb heat, gain energy, and begin to move apart, transitioning from a solid to a liquid.

What happens to molecules during freezing?

Back

During freezing, molecules lose energy, slow down, and come closer together, transitioning from a liquid to a solid.

What is vaporization?

Back

Vaporization is the process where a liquid turns into a gas, either through boiling or evaporation.

What is condensation?

Back

Condensation is the process where a gas turns into a liquid, typically when it cools down.

What is the difference between boiling and evaporation?

Back

Boiling occurs at a specific temperature throughout the liquid, while evaporation can occur at any temperature and only at the surface of the liquid.

Front

What is plasma?

Back

Plasma is a state of matter where gas is energized to the point that some electrons are freed from their atoms, resulting in a mixture of charged particles.
