States of Matter and Kinetic Energy

Front

What are the three main states of matter?

Back

Solid, Liquid, Gas.

Front

What happens to particles in a solid?

Back

Particles are closely packed together and vibrate in place.

Front

What happens to particles in a liquid?

Back

Particles are close together but can move past each other, allowing liquids to flow.

Front

What happens to particles in a gas?

Back

Particles are far apart and move freely, filling the space available.

Front

What is thermal energy?

Back

The total energy of all the particles in a substance, related to temperature.

Front

What occurs when a substance gains thermal energy?

Back

The particles move faster and may move further apart.

Front

What occurs when a substance loses thermal energy?

Back

The particles move slower and may come closer together.

Front

What is kinetic energy?

Back

The energy of motion; the faster an object moves, the more kinetic energy it has.

Front

How does temperature relate to kinetic energy?

Back

Higher temperature means higher kinetic energy as particles move faster.

Front

What is the process of melting?

Back

The change from solid to liquid when a substance gains thermal energy.
