Front

Describe the arrangement of particles in a solid state of matter.

Back

Particles are closely packed together in a fixed position.

Front

How do particles behave in a liquid state of matter?

Back

Particles are close together but can move past one another, allowing liquids to flow.

Front

What is the characteristic of gas particles in terms of spacing?

Back

Gas particles are far apart and move freely.

Front

What happens to matter when heat is added?

Back

Matter can evaporate or change from a solid to a liquid or gas.

Front

What is condensation in terms of matter?

Back

Condensation is the process where gas turns into a liquid when heat is removed.

Front

What is the process called when a solid changes directly to a gas?

Back

Sublimation.

Front

What happens to the energy of particles as temperature increases?

Back

The energy of particles increases, causing them to move faster.

Front

What is the term for the temperature at which a solid becomes a liquid?

Back
