Question

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

here is my answer:

temperature increase makes particles move faster and spread a part

Please edit

Answer 1

I think it looks ok. I might stick in the kinetic energy because everyone likes to see that term used.

Increases in temperature adds kinetic energy to the particles and that makes them move faster and move further apart if they are not in an enclosed container.

Answer 2

i agree
