What are the three main states of matter?

Back

Solid, Liquid, Gas.

Front

How do particles behave in a solid?

Back

Particles are closely packed and vibrate in fixed positions.

Front

What happens to the movement of particles in a liquid compared to a solid?

Back

Particles in a liquid move more freely than in a solid.

Front

What is kinetic energy?

Back

The energy that an object possesses due to its motion.

Front

How does temperature affect the movement of particles?

Back

As temperature increases, the movement of particles increases.

Front

What occurs to the spacing of particles when a substance is heated?

Back

The spacing between particles increases.

Front

What is the effect of decreasing temperature on the movement of particles in a liquid?

Back

The movement of particles decreases.

Front

What is a characteristic of gas particles?

Back

Gas particles move rapidly and are widely spaced.

Front

What happens to the kinetic energy of particles when thermal energy is added?

Back

The kinetic energy of particles increases.

Front

How do particles in a gas differ from those in a liquid?

Back

Gas particles are much farther apart and move freely compared to liquid particles.
