Energy and Phase Change Flashcard

Front

What is the arrangement of particles in solids compared to gases?

Back

Particles in solids are tightly packed, while particles in gases are spread out.

Front

What phase change occurs at the plateau of a cooling curve?

Back

Freezing.

Front

How does particle motion in liquids compare to that in plasmas?

Back

Particles in plasmas move more freely than in liquids.

Front

What is a primary benefit of using nuclear energy as an alternative energy source?

Back

It has a high energy output with low carbon emissions.

Front

Why is copper used in electrical wiring?

Back

Copper has a low specific heat, allowing it to conduct electricity efficiently.

Front

Define specific heat.

Back

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is the process of melting?

Back

Melting is the phase change from solid to liquid.

Front

What is vaporization?

Back

Vaporization is the phase change from liquid to gas.

Front

What is sublimation?

Back

Sublimation is the phase change from solid directly to gas.

Front

What happens to particle motion during freezing?

Back

Particles lose energy and move closer together.
