Front

What causes thermal expansion?

Back

The particles move faster.

Front

When a substance is heated, what happens to the particles?

Back

The particles speed up and spread out.

Front

In which state of matter can particles slide by each other but are held together?

Back

Liquid.

Front

What causes thermal contraction?

Back

The particles get slower.

Front

Instead of saying it is hot outside, what should we say?

Back

The air particles are moving fast.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

How does temperature affect the kinetic energy of particles?

Back

As temperature increases, the kinetic energy of particles increases.

Front

What happens to the volume of most substances when they are heated?

Back

The volume increases.

Front

What is the relationship between particle movement and temperature?

Back

Higher temperature means faster particle movement.

Front

What is a solid?

Back

A state of matter where particles are closely packed and vibrate in place.
