Front

What is the relationship between particle movement and thermal energy?

Back

The faster the particles move, the warmer the matter becomes.

Front

Front

How does the energy of particles in a solid compare to that in a gas?

Back

Particles in a solid have less energy than those in a gas.

Front

What happens to the thermal energy of a substance when it is heated?

Back

The thermal energy increases, causing the particles to move faster.

Front

What is the process called when a solid turns into a liquid?

Back

Melting.
