Thermal Energy and Particle Motion Flashcard

Front

What happens to the particles inside a balloon when it is heated?

Back

The particles inside the balloon move faster and take up more space.

Front

What will happen to the state of water if thermal energy is continuously removed from it?

Back

It will change from liquid to solid.

Front

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

Back

They vibrate more rapidly.

Front

Which state of matter has a definite shape and volume?

Back

Solid.

Front

What is an example of a physical change?

Back

Melting ice.

Front

Define thermal energy.

Back

Thermal energy is the total kinetic energy of the particles in a substance.

Front

What is the relationship between temperature and particle motion?

Back

As temperature increases, particle motion increases.

Front

What happens to the volume of a gas when it is heated?

Back

The volume of a gas increases when it is heated.

Front

What is the state of matter with no definite shape or volume?

Back

Gas.

Front

What occurs during a phase change from solid to liquid?

Back

The particles gain energy and move apart.
