Unit 5 BR #1 Modeling matter

Front

What happens to the motion of particles in ice cream when it is placed in the freezer?

Back

The particles slow down and move closer together.

Front

How is the transition between a liquid state and a gaseous state best described?

Back

Liquid state to gaseous state.

Front

What happens to the molecules of a solid when it is heated?

Back

Particles move further from each other and the pattern within the structure of solid molecules changes.

Front

What is the most accurate particle diagram for the element Neon?

Back

Diagram A.

Front

What composes an element?

Back

Atoms of the same structure.

Front

Define 'solid state' in terms of particle motion.

Back

In a solid state, particles are closely packed and vibrate in fixed positions.

Front

What occurs during melting?

Back

A solid changes to a liquid as particles gain energy and move apart.

Front

What is the process of condensation?

Back

The transition from a gas to a liquid as particles lose energy and come closer together.

Front

Explain the term 'gas state' regarding particle arrangement.

Back

In a gas state, particles are far apart and move freely.

Front

What is the effect of temperature on particle motion?

Back

Increasing temperature generally increases particle motion.
