how would you describe change in a arrangement of particles as heat energy and temperature increases.

here is my answer:

particles diffuse and increase speed.

please edit

They do increase in energy, and that is movement of some sort. At higher temperatures, this movement forces the particles apart by greater distances.

Your answer is partially correct, but it could use some further clarification. When the temperature of a substance increases, the particles within that substance gain more energy. This increased energy causes the particles to move faster and more vigorously, resulting in an increase in their speed and kinetic energy. Additionally, as the particles gain more energy, they are more likely to escape the attractive forces holding them together, leading to an increase in diffusion. So, to describe the change in the arrangement of particles as heat energy and temperature increases, you can say that the particles exhibit increased speed, increased kinetic energy, and increased diffusion.
