Phases and Phase Changes Flashcard

Front

What type of motion do particles in a liquid exhibit?

Back

Medium Motion

Front

What is the term for a change from solid to gas without passing through the liquid phase?

Back

Sublimation

Front

Describe the motion of particles in a plasma state.

Back

Very, Very Fast Motion

Front

If sulfur has a melting point of 215 °C, what phases of matter can it exist in at this temperature?

Back

Both Solid and Liquid

Front

What happens to the particles of a phase of matter when kinetic energy is added?

Back

They move faster.

Front

What is the definition of a phase change?

Back

A transition of matter from one state to another, such as solid, liquid, or gas.

Front

What are the four main phases of matter?

Back

Solid, Liquid, Gas, Plasma

Front

How does temperature affect the phase of matter?

Back

Increasing temperature generally increases kinetic energy, which can change the phase from solid to liquid to gas.

Front

What is the relationship between kinetic energy and temperature?

Back

Kinetic energy is directly proportional to temperature; as temperature increases, kinetic energy increases.

Front

What is the process called when a gas turns into a liquid?

Back

Condensation
