As the temperature of the material increases, the particles move
The answer is: increased.
As the temperature of a substance increases, the particles move faster and with more energy. This is due to the fact that as the temperature increases, the molecules of the substance gain kinetic energy and begin to move more quickly. This results in greater particle movement, which can be observed with the naked eye. The relationship between temperature and particle movement is direct, meaning that as temperature increases, particle movement also increases.
