When a substance's thermal energy is increasing, what is occurring at the particle level?
draw a particle diagram to aid your written explanation.

With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly. The attractive force in solids need not be stronger than in liquids or gases. For example the forces between solid helium particles (at -270 degrees C) are still very weak.

i cant draw it tho sorry hope this helps if you want we can talk cuz im bored

Explanation:

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

i think so it’s will be b yes i believe its
