Front

Describe the particle arrangement in solids.

Back

Particles are closely packed together in a fixed position.

Front

Describe the particle arrangement in liquids.

Back

Particles are close together but can roll over each other.

Front

Describe the particle arrangement in gases.

Back

Particles are far apart and move freely.

Front

What is the defining characteristic of solids?

Back

Definite shape and definite volume.

Front

What is the defining characteristic of liquids?

Back

No definite shape and no definite volume.

Front

What happens to the temperature during an exothermic reaction?

Back

The temperature increases.

Front

What is absolute zero?

Back

The theoretical temperature at which particles have minimum thermal motion.

Front

What is the relationship between particle motion and temperature?

Back

As temperature increases, particle motion increases.
