Particles in Motion_Thermal Energy

Front

As temperature increases, what happens to kinetic energy?

Back

Kinetic energy increases.

Front

True or False: The faster the particles move, the less kinetic energy there is.

Back

False.

Front

What happens to a liquid in a thermometer when it is warmed?

Back

The liquid expands.

Front

In diffusion, when does it complete?

Back

Diffusion is complete when the particles are evenly distributed.

Front

As the kinetic energy of the particles increases, what happens to the speed of the particles?

Back

The speed of the particles increases.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is thermal energy?

Back

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

Front

What is diffusion?

Back

Diffusion is the process by which particles spread from areas of high concentration to areas of low concentration.

Front

How does temperature affect the movement of particles?

Back

As temperature increases, particles move faster.

Front

What is the relationship between temperature and thermal energy?

Back

As temperature increases, thermal energy increases.
